I'd be interested to know why you want to do this.  There might be a
better way to tackle the problem.  For example, and XML instance along
the lines of <data name="foo" value="bar"/> might work.

Coming back to the problem as ou stated, if you do
processContents="strict" then you will have to have a definition of
the element somewhere for validation to complete.  This would be the
only way you could restrict the type of the element as well.  With
that in mind, you might be able to define an xs:group that defines all
your possible extra elements.

BTW - when using xs:any to allow elements in your existing namespace,
you have to worry about the Unique Particle Attribution Constraint, or
UPAC.  Annoyingly, if you have an element prior to your xs:any that
does not have fixed cardinality (i.e. minOccurs and maxOccurs are not
the same value) then the xs:any will be in conflict with that element
and the schema won't be valid!

Other than that, can you not do namespace="##any" on your xs:any
statement?
