Yes, it's rarely used, but in XPath 1.0 it's the only way to discover what namespaces have been declared in your source document. This is essential if the document uses "namespace prefixes in content". > > If you use it, how? > What makes it worthwhile in xslt 2.0? > It's (sadly) deprecated in XPath 2.0 - largely at the instigation of implementors who couldn't see how to implement it efficiently - and replaced by custom functions such as in-scope-prefixes() and resolve-QName(). But I've no intention of getting rid of it in Saxon. Regards, Michael Kay http://www.saxonica.com/ http://twitter.com/michaelhkay
