[xsd-users] --generate-comparison and anyType

[Ray Lischner]

We are using Code Synthesis 3.3.0. When I use --generate-comparison and an element has type anyType, the generated comparison function does not compile because xml_schema::type does not have the == operator. I don't know what it means for an anyType to == an anyType, so I don't know the solution to this problem, but I think it a real problem when a valid schema compiles to invalid C++ without a peep from xsd.

demo.xsd
<schema xmlns=http://www.w3.org/2001/XMLSchema xmlns:sample="urn:demo" targetNamespace="urn:demo"/>
  <complexType name="Type">
    <sequence>
      <element name="a" type="anyType"/>
      <element name="b" type="int"/>
    </sequence>
  </complexType>
</schema>

xsd cxx-tree --generate-comparison demo.xsd
g++ -c -Ixsd demo.cxx
demo.cxx: In function 'bool demo::operator==(const demo::Type&, const demo::Type&)':
demo.cxx:204: error: no match for 'operator==' in '((const demo::Type*)x)->demo::Type::a() == ((const demo::Type*)y)->demo::Type::a()'
