W3C XQuery Novermber 2003 Draft

The XQuery documentation says that Tamino supports the Novermber 2003 XQuery Draft.


However, I find that some functions like ‘concat’ are not there in the Tamino documentation.

Is there a reason for this? Where can I get a list of unsupported XQuery functions in Tamino.

In the XQuery 4 reference there?s a section on ?XQuery 4 Implementation Status?; the path within the distributed Documentation folder is ?xqueryref/xqr-status.htm?. Although it says it is not a complete list, and, in fact, it doesn?t mention ?concat?.
