	Web Service Definition Language (WSDL)
		WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information.
		WSDL is extensible to allow description of endpoints and their messages regardless of what message formats or network protocols are used to communicate, however, the only bindings described in this document describe how to use WSDL in conjunction with SOAP 1.1, HTTP GET/POST, and MIME.
		WSDL recognizes the need for rich type systems for describing message formats, and supports the XML Schemas specification (XSD) [11] as its canonical type system.

	Web Services Description Language - Wikipedia, the free encyclopedia
		WSDL is an XML-based service description on how to communicate using the web service; namely, the protocol bindings and message formats required to interact with the web services listed in its directory.
		Any special datatypes used are embedded in the WSDL file in the form of XML Schema.
		XLang is an extension of the WSDL such that "an XLANG service description is a WSDL service description with an extension element that describes the behavior of the service as a part of a business process" [1].

		For example, WSDL descriptors express service semantics in a neutral format so that interfaces defined in Java, for instance, to be mapped and understood by a client built using.NET.
		WSDL is IDL for web services, and it should be used as such.
		Using WSDL first, no component is ever more than a single generation away from the source document, and whatever imprecision exists in a given mapping -- while potentially irritating to the programmer -- will have limited impact.

	webservices.xml.com: Emerging Technology Briefs: WSDL (Site not responding. Last check: 2007-10-13)
		WSDL is the de facto description mechanism in the current Web Services SOAP/WSDL/UDDI trinity (or quaternity if you assume HTTP as the default transport mechanism).
		While WSDL is not endorsed by the W3C as a standard, just about every player in the Web Services space has embraced WSDL and incorporated it into their frameworks and products.
		WSDL 1.1, the version of WSDL in widespread use today, was published as a W3C Note in March of 2001 and may be taken, for all intents and purposes, to represent current thinking in Web Services description by the W3C's Web Services Activity.

	Defining Web services in WSDL: A primer
		WSDL is also protocol-neutral, but it does have built-in support for binding to SOAP, making it rather irrevocably associated with it.
		WSDL has been submitted to the Internet-standards body World Wide Web Consortium (W3C), where its official status is that of Acknowledged Submission.
		In WSDL parlance, a message can be any parameter passed to a method on an object the service exposes, or any result returned by the invocation of that method.

	WSDL Essentials
		WSDL therefore represents a cornerstone of the web service architecture, because it provides a common language for describing services and a platform for automatically integrating those services.
		WSDL is not tied exclusively to a specific typing system, but it uses the W3C XML Schema specification as its default choice.
		WSDL Version 1.1 was submitted to the W3C in March 2001.

	Web Services Description Language (WSDL) Version 2.0 Part 1: Core Language
		WSDL 2.0 enables one to separate the description of the abstract functionality offered by a service from concrete details of a service description such as “how” and “where” that functionality is offered.
		Assertions about WSDL 2.0 documents and components that are not enforced by the normative XML schema for WSDL 2.0 are marked by a dagger symbol (†) at the end of a sentence.
		The set of top-level components contained in the Description component associated with an initial WSDL 2.0 document consists of the components defined in the initial document and the components associated with the documents that the initial document includes and the namespaces that the initial document imports.

	wsdlpull - A C++ WSDL Library
		Both the API and the tool are very dynamic and allow invocation of WSDLs which have complex types and simple types in the schema.Using the wsdl tool you can invoke complex web services from command line without writing any code.
		The WSDL parser provides APIs to access various WSDL elements such as operations,messages,bindings,port types.Although wsdlpull is based on the pull parsing style of xml parsing the API is meant to be semantically as close as possible to the standard API for parsing WSDL,namely WSDL4J.
		If the fix is in the wsdl parser then invoke the web services in the test/wsdls directory and check if they work You must atleast test one RPC style web service and one Doc/Literal style from the test suite.

	Overview of WSDL
		WSDL is extensible to allow description of endpoints and their messages regardless of what message formats or network protocols are used to communicate."
		A Java API for WSDL (JWSDL) specification is currently in the works in the Java Community Process (JCP).
		With the WSDL document in hand, the Java programmer can then feed it to a tool that can generate a Java object proxy to the Web service, or simply use it as a reference document along with a lower-level SOAP API.

	Web Services Description Language (WSDL) Version 2.0 Part 1: Core Language
		An XML 1.0 document that is valid with respect to the WSDL 2.0 XML Schema and that maps to a valid WSDL 2.0 Component Model is conformant to the WSDL 2.0 specification.
		The declaration of an operation in a WSDL 2.0 interface is not an assertion that the interaction described by the operation must occur.
		Description component associated with an initial WSDL 2.0 document consists of the components defined in the initial document and the components associated with the documents that the initial document includes and the namespaces that the initial document imports.

		WSDL Explorer displays the port types and operations as a tree in a navigation frame, and it displays a form view for a selected operation in a content frame.
		WSDL derives from two earlier efforts by a number of companies; the current de facto standard is a W3C Note submitted by IBM and Microsoft.

	Web Services Description Language (WSDL) 1.0
		This version of the WSDL language is a first step that does not include a framework for describing the composition and orchestration of endpoints.
		The authors of the WSDL specification intend to publish revised versions of WSDL and/or additional documents in a timely fashion which will include a (1) framework for composing services and a (2) framework for describing the behavior of services.
		It is not necessary to exhaustively list all headers in this section; it may be common that other specifications in the WSDL document cause headers to be added to the actual payload and it is not required to list those headers here.

	PerfectXML.com - Web Services: WSDL, UDDI, DISCO and more
		The Web Services contract written using WSDL is an XML document that defines the inputs and outputs of a Web Service, including the XML Schemas that should be used to create the input and output documents.
		WSDL is exactly like the IDLs of the past in that a WSDL document describes the portTypes or interfaces a web service implements.
		However, there is one critical difference between WSDL and the IDLs distributed systems developers know and love: no one wants to use WSDL as a starting point.

	Web Services Description Language Tool (Wsdl.exe)
		The WSDL alone implements the WSDL contract (classes that implement the interface should not include either of the following on the class methods: Web Service attributes or Serialization attributes that change the WSDL contract).
		WSDL documents are added in the /parameters WSDL file using the element, as the following code example demonstrates.
		In this case, the file enables the new style of databinding in proxy code, and specifies a schema importer extension, that output is not to be verbose, and that Wsdl.exe is to create a client proxy.

	Web Services Description Language (WSDL) Version 1.2 Part 0: Primer
		It is intended as a non-normative companion to the official WSDL 1.2 specification, for readers who wish to have an easier, less technical introduction to the main features of the language than the official specification provides.
		WSDL 1.2 does not address the problem of Web service discovery, but WSDL 1.2 is intended to be used by discovery mechanisms that provide additional value to a client seeking a particular kind of Web service.
		This section introduces the WSDL 1.2 mechanisms for defining an abstract interface to a Web service, independeint of the specific Web address and transport protocols that are used to implement the Web service.

	Pod::WSDL - Creates WSDL documents from (extended) pod - search.cpan.org
		WSDL differentiates between in-, out- and inout-parameters, so we do that, too.
		Return values work like parameters but since in WSDL there is provision for only one return value (you have (in)out parameters, or can return arrays if that isn't enough), you do not need to give them a name.
		WSDL provides the means to describe complex types borrowing the xsd schema syntax.

		In fact, WSDL is specifically designed for maximum flexibility and is therefore not tied exclusively to any one data type system.
		Example 6-6, shown later in this section, is a sample WSDL file that illustrates the use of arrays.
		The WSDL specification requires that arrays be based on the SOAP 1.1 encoding schema.

	WDVL: Web Services Essentials
		WSDL is a specification defining how to describe web services in a common XML grammar.
		In a nutshell, WSDL represents a contract between the service requestor and the service provider, in much the same way that a Java interface represents a contract between client code and the actual Java object.
		Figure 6-1 offers a concise representation of the WSDL specification.
