You *would* say that, wouldn't you, Paul :) Perhaps more practical advice (in terms of current implementations) would be to use something that claims XQL or XPath support. The problem is that, whether you like it or not, you probably won't find two implementations of either (as a standalone query language) that act exactly the same. At least theoretically, you won't find true interoperability until after XQuery becomes a Recommendation. The reason I suggest XQL or XPath, as opposed to XML-QL, is that XQuery's path expressions are closely related to these and should afford you an easier transition, both semantically and syntactically, once XQuery becomes ready for prime time. Also note that the draft XPath 2.0 Requirements document states, in section 1.2, that XPath 2.0 "Must Provide Common Core Syntax and Semantics for XSLT 2.0 and XML Query 1.0". See http://www.w3.org/TR/xpath20req XPath 1.0 is a W3C Recommendation in wide use, within XSLT. See http://www.w3.org/TR/xpath XQL is not a W3C work but has a common heritage with XPath.
