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

that is correct, if you see
http://www.w3.org/TR/xmlschema-1/#coss-identity-constraint

it says selector can include |, but field cannot include |. This is to be
expected, right?, from what is the general principle: any path expression
in the field should return one and exactly one value.
