Subject: RE: [xsl] Can XPath / XSLT be aware of XML Schema content models grouping i nformation ? From: Jerome Louvel <Jerome.Louvel@xxxxxxxxxxxxxx> Date: Fri, 9 Nov 2001 10:38:18 -0500 |
Thanks Jeni for your comments. In fact this is more an hypothetical problem that we may encounter than a real world requirement. However after reading the article on James Clark in DDJ "A Triumph of Simplicity: James Clark on Markup Languages and XML" http://www.ddj.com/documents/s=862/ddj0107e/0107e.htm I'm now wondering if this inclusion in XPath/XSLT 2.0 would be a good thing, especially if you consider XML Schema as just one way to constrain / validate an XML document compared to Relax NG, Schematron, XDR, ....

There's certainly not in XSLT 1.0. For XPath/XSLT 2.0 to support it, the XQuery/XPath data model would have to include model groups. The only schema components that it does so far (see the WD at http://www.w3.org/TR/query-datamodel/#types) seems to be element/attribute declarations and simple/complex types. So it doesn't look as though there's a plan to have this support at present. But you should bring it up to the XQuery/XPath editors (www-xml-query-comments@xxxxxx). The schema support in XPath/XSLT should reflect real world requirements, and if you've got one, then you should make your case!
