Extra: XPath 2.0
The future of XPath within the W3C family of XML technologies seems secure. The use of XSLT is already well established and seems likely to grow progressively for the foreseeable future.
The future of XPath is importantly interlinked with the emerging XML Query Language, XQuery. The first Working Draft for XPath 2.0 was issued shortly before this writing. The XPath 2.0 data model and the XPath 2.0 functions and operators drafts have been issued as a joint document for XPath 2.0 and XQuery 1.0.
XQuery is described in more detail in Chapter 21.
