RE: Abstract Interpretation of XSLT stylesheets
> XSLT is a declarative language, not a functional language. Think SQL. I think that's open to debate. XPath is certainly declarative, and the pattern-matching template rules of XSLT could also be described as declarative, but the call-template mechanism and the way variables and parameters work has a strong "functional" feel to it, even though the inability to manipulate functions as values means that it's not a fully-fledged functional programming language. Incidentally, while the SELECT statement in SQL is declarative, procedures in SQL are rather heavily procedural. Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
