    http://www.w3.org/TR/xquery-operators/ defines op:anyURI-equal(anyURI $srcval1, anyURI $srcval2) => boolean Returns true if $srcval1 and $srcval2 compare equal on a codepoint-by-codepoint basis. Else returns false. This function backs up the "eq" and "ne" operators on anyURI. It looks to me from earlier in the document as if "codepoint" just means one "character" from the string encoding being used. So this will match character by character. So anyURI-equal will not expand the QNames itself. Unless we find a reference that says QNames in XML attributes MUST be expanded before semantic processing of the XML document, then I guess we need to put this description somewhere.
