Re: [xml-dev] having problems with the "|" in field's element in the xs:key el ement

Your basic approach is fine.  There are various minor errors in your
schema, and of course it was incomplete.  If I fix all that (see
below), XSV is happy with your instance, and correctly finds an error
if I change the content of the 2nd pickSurfName so it's the same as
the first:

  <invalid char="9" code="cvc-identity-constraint.2.2.3" line="13"
    resource="keyOr.xml">duplicate key (1L, u'LGC', u'C SAND') for
 {http://www.lgc.com/schema/OpenWorksData/2003}Pick_InHierarchy_Key_Definition,
 first appearance was in unnamed entity at line 4 char 9 of keyOr.xml</invalid>
