This is in fact one of my main worries about this whole schema-awareness idea for xpath 2. using keys in XSLT turns out to be a lot more useful than using id() not just because they are more general but importantly because a large part of xslt processing is done with non validating parsers that might or might not read any DTD. I'm all in favour of XPath being aware of schema datatypes (lists and doubles and dates etc) but I'd hate to see XSLT processing requiring schema processing as a norm, and I hope to see easy ways of casting things to the datatype (for simple datatypes) from within XSLT (or XPath) just as xsl:key might be seen as a XSLT generalisation of an ID attribute declaration in a DTD. Of course without an XPath 2 draft (Mike, where are you:-) it's all a bit hard to say. It's also hard to make any sensible comments on the drafts that are public (like functions and operators) without seeing a draft of the language in which these functions are supposed to live.
