In section 3.14.2 of http://www.w3.org/TR/xmlschema-1/ it says "{any

<simpleType name="myName" xyz:myattribute="something">

Exactly!

I was not aware of this feature before. In fact, if the
above is true, it is not possible to validate an XML Schema (which itself is an
XML document) against a DTD because there is no way to specify in a DTD that an
element can have any attributes.
[JMC] Why would you want to
validate an XML against a DTD, when an XML schema validator will serve this
purpose? The obvious question is why would
you need attributes outside the XML Schema specification ?
[JMC] That's actually a
rather unclear question. The XML Schema specification includes the ability to
declare attributes. You declare attributes as you need, as long as your XML
schema conforms to the W3C Schema specification. Sounds like you are thinking
one "meta" layer too far.

If you extend an XML Schema in such a way then you defeat one of the
main goals of XML, which is to be portable (only you tool will understand the
custom attributes)
