It's not uninteresting, simply or otherwise :), but the notion of "validating an XSLT stylesheet" makes sense only if the result tree uses XSL formatting objects. An overall DTD for XSL -- covering XSLT and the formatting objects -- is possible, but the question is complicated by the ability of XSLT to produce result trees in *non*-XSL vocabularies. What you end up with in such a stylesheet contains elements and attributes from two different DTDs. About the best you can do with this stylesheet is to test it for well-formedness. (To my knowledge, there's not yet a validating parser that's capable of validating against more than one DTD at a time. For starters, what do you put in the document-type declaration?) So the answer isn't that it's uninteresting. The answer is that since many (probably most) XSLT spreadsheets generate (X)HTML result trees, at least so far, validation isn't even possible. ==================== John E.
