Practically, no, because (a) there isn't going to be another XSLT specification in the foreseeable future, and (b) there wouldn't be enough implementors to justify a standard. Technically, schema validation is closely tied in with the XDM type system, and this has the consequence that XDM never exposes nodes for which validation has failed (that is to say, for which the outcome of validation is "invalid"). It would be possible to relax this, but it would need careful thought: it would involve a different kind of validation, in which (a) validation never causes a dynamic error, but (b) data that has been subjected to validation cannot be assumed to conform to the type against which it was validated. There is also an effect on streaming. XSD is designed so that you know, while processing a start tag, what the type of the element is supposed to be; but you don't know until you hit the end tag whether the element is actually valid against that type. This means that if invalid data is to be made visible to the application, then in a streaming environment the PSVI data for an element can't be exposed until you reach the end tag. Of course, there are applications for which it would be very useful to allow an invalid document to be processed and inspected, but it's probably a minority requirement.

My naive feeling is, XSLT should provide a way to know, all prescribed PSVI information mention in XML Schema language. Is it practical to have this required, in the future XSLT spec (like XSLT 3.0 2nd Edition or something similar)? > > > > -- > Regards, > Mukul Gandhi > XSL-List info and archive <http://www.mulberrytech.com/xsl/xsl-list> > EasyUnsubscribe <-list/293509> (by email <>)
