The World Wide Web Consortium released XPointer as a three-part W3C Recommendation. The “XPointer Framework” is an extensible system for identifying regions in XML documents which provides for multiple addressing schemes. The “element()” scheme allows basic addressing of XML elements in terms of a document’s tree structure. The “xmlns()” scheme is used to interpret namespace prefixes in scheme names and pointers. www.w3.org/TR/2003/REC-xptr-framework-20030325/
