      Description

      Name: erR10175 Date: 06/03/2002


        TCK test
      api/xml_schema/structures/ElemDecl/substGroupExclusions/substGroupExclusions003/substGrpExcl00301m/substGrpExcl00301m2.html#Negative

      shows that if both restriction and extension are ruled out, the declaration
      may be nominated as the {substitution group affiliation} of *another* declaration
      with the same type.

      But the specification (XML Schema Part 1: Structures, 3.3 Element Declarations) reads:
      "An empty {substitution group exclusions} allows a declaration to be nominated as the
      {substitution group affiliation} of other element declarations having the same
      {type definition} or types derived therefrom. The explicit values of
      {substitution group exclusions} rule out element declarations having types which are
      extensions or restrictions respectively of {type definition}. If both values are specified,
      then the declaration may not be nominated as the {substitution group affiliation} of
      *any* other declaration."

      To reproduce the bug validate the following schema and document.
      The validation unexpectedly passes without an error.
