[xsl] Re: [Bulk] Re: [xsl] XPath "validation"

["Anthony B. Coates (XSL-List)" <abcoatesecure-xsllist@xxxxxxxxxxx>]

I did, but never fully finished it, in the sense that it works for a lot  
of Schemas, but not fully for some of the more complex examples that I  
have (e.g. FpML).

I'm not sure if 'xmlzebra.com' is still working, but if anyone is  
interested to try it out, please do let me know (abcoates.work @  
yahoo.co.uk) and I will keep it live.  Any feedback would be very welcome.

Thanks, Cheers, Tony.
