I've always assumed that the only reason for testing function-available() was because you wanted to call the function, and since the function call has to use a static name, there's no conceivable reason to use function-available with a dynamic name. Perhaps I was wrong. From the link I just send, I think more people tried it the way Jim tried it, I quote from XALANJ-2223: "I wrote a stylesheet whose only purpose is to call "function-available" on the EXSLT functions specified in an XML file. I first tested this in Stylus Studio, using the Xalan 2.5.2 engine. When I run it, I get: functionAvailable.xsl (19, 48): java.lang.RuntimeException: Unknown error in XPath." Perhaps this is the only niche where it makes sense to do it dynamically? Cheers, -- Abel Braaksma
