You need

   <xs:anyAttribute namespace="##local" processContents="lax"/>

The default for processContents is 'strict', which in turn means "any
unprefixed attribute, provided I can find a top-level declaration for
it".

With that change, XSV is happy with your example.

Yes, use namespace="##any".
