hey:

I tried to use Xerces2 to validate the personal.xsd schema which come with
the Xcerces2 distribution. But got the error cvc-elt.1: Cannot find the
declaration of element 'xs:schema'.

On the old version Xerces faq site
http://xml.apache.org/xerces-j/faq-general.html it says
"We hope to introduce functionality to permit schemas to be validated
independently of instance documents in Xerces2".

So does the Xerces2 really can validate schemas independently? If yes, how?

Thanks.

The personal.xsd:
