| | XML.com: The XPath 2.0 Data Model |
 | | The XPath 1.0 Recommendation's Data Model section, which is about six pages when printed out, provides a subsection for each possible node type in the XPath representation of an XML tree: root nodes, element nodes, text nodes, attribute nodes, namespace nodes, processing instruction nodes, and comment nodes. |
 | | This part of the data model has actually simplified a messier aspect of XPath 1.0, and we've already seen the payoff in an earlier column on using temporary trees in XSLT 2.0. |
 | | The data model document talks a lot about retrieving the values of node properties with "accessors," which are abstract versions of functions that represent ways to get the values of node properties. |
