Yes, but not legal XPath 1.0, which would mean that all implementors would have to retrofit not just extensions, but their XPath implementation cores with entirely speculative syntax. Why would anyone go this byzantine route when they can just allow XSLT control structures? > What I'm arguing is that a couple of non-intrusive extensions > to XPath is preferable to an intrusive mix of XPath and XSLT > instructions.

I proposed a functional rather than a structural constraint, which would mean absolutely no damage to existing XSLT content model. -- Uche Ogbuji Principal Consultant uche.ogbuji@xxxxxxxxxxxxxxx +1 303 583 9900 x 101 Fourthought, Inc. http://Fourthought.com 4735 East Walnut St, Ste.
