  Regular Language description for XML - Wikipedia, the free encyclopedia
REgular LAnguage description for XML (RELAX) is a specification for describing XML-based languages.
A description written in RELAX is called a RELAX grammar.
RELAX Core has been approved as an ISO/IEC Technical Report 22250-1.

 XML Schema languages
One of the key strengths of XML (sometimes called late "binding") is the decoupling between the writer and the reader of a XML document which gives to the reader the ability to have its own interpretation and understanding of the document.
Defined in the XML 1.0 recommendation, they do not support namespaces which have been specified after them and this is, with the fact that their datatype system is weak and does only apply to attribute, one of the main motivation of the W3C to develop a new schema language.
W3C XML Schema is a strongly typed schema language which has chosen to eliminate any non-deterministic design from the described markup to insure that there is no ambiguity in the determination of the datatypes and that the validation van be made by a finite state machine.

 Cover Pages: SGML/XML and Forest/Hedge Automata Theory
They are regular expressions such that each 'symbol' is a triplet (e1, a1, e2), where e1 e2 are hedge regular expressions and a is a condition on nodes.
In the XML terminology, a hedge is a sequence of elements possibly intervened by character data (or types of character data).
XML documents are composed of nested elements and the logical structure of elements is defined by Document Type Definitions (DTDs).

 Cover Pages: Regular Language Description for XML (RELAX)
RELAX (REgular LAnguage description for XML) is a namespace-aware specification for describing XML-based languages which borrows rich datatypes from XML Schema Part 2; the RELAX grammar can be written as an XML document.
Relaxer is the Java class generator that addresses a XML document complied with the XML model defined by RELAX.
The RELAX Verifier can validate XML document against RELAX grammar, reporting errors in XML documents and their locations; it can be used both from an application and command-line.

 XML Sucks - The Big List of XML Technologies
Obsolete schema language, deprecated in favour of XML Schema.
An XML language for describing the schemas (in various formats) which apply to elements in a particular namespace, and for combining these so that the validitity of a composite XML document can be checked.
It is now standard practice for XML vocabularies to specify a namespace URI for their elements, so that processors can pick out the data for a particular format and leave everything they don't understand unchanged.

The authoritative description is the schema for datatype definitions in Appendix A of XML Schema part 2.

 RELAX NG is "Relaxing" - UG Book Review
The beauty of XML is that it is extensible, even to the point that developers can invent new elements and attributes as they write XML documents.
"XML schema languages are a nice idea as long as they don't become so complicated that XML vocabularies built using them are difficult to extend," says van der Vlist.

 Discover RELAX NG, A Simple Schema Solution
With the goals of compact syntax and compatibility, the Regular Language Description for XML (RELAX NG) eases the pain of working with cumbersome DTDs and XSDs.
While XSD (XML Schema Definition) was developed to define schemas in the XML format, RELAX NG supports pluggable simple data type libraries (new ones can be readily designed and built as needed) and provides two interconvertible syntaxes: an XML one for processing and a compact non-XML one for human authoring.
An XML document is represented by an element, which consists of a name, context, a set of attributes, and an ordered sequence of zero or more children.

 "RELAX NG": A Simpler Schema Language for XML
Sebastopol, CA--The beauty of XML is that it is extensible, even to the point that developers can invent new elements and attributes as they write XML documents.
In his new book, RELAX NG (O'Reilly, US $29.95), author Eric van der Vlist introduces the Regular Language Description for XML Core--New Generation, or RELAX NG (pronounced "relaxing"), an alternative to other schema languages that's quickly gaining momentum.
In "RELAX NG," developers are introduced to this unique language and will learn a no-nonsense method for creating XML schemas.

 HOW TO RELAX
The input to the RELAX processors is an XML document and a RELAX grammar.
To be precise, the RELAX processor does not directly handle XML documents and RELAX grammars, but rather receives the output of the XML processor which handles them.
Some of the built-in datatypes of XML Schema Part 2 are borrowed from XML DTD; the others are newly introduced.
