Hi Roger,

This limitation is somewhat alleviated with XSD 1.1 xs:assertion facet.

For e.g,

      <xs:restriction base="xs:string">
	    <xs:assertion test="matches($value, 'R1')"/>
	    <xs:assertion test="matches($value, 'R2')"/>
	    <xs:assertion test="matches($value, 'R3')"/>

(R1, R2 & R3 are some regex's)

In this case, matches(..) works like xs:pattern but all xs:assertion
's are ANDed (unlike xs:pattern which are OR-ed).
