[xsd-users] ##any type problems

[Bradley Beddoes]

Hi,
I am attempting to compile a schema using XSD and am running into 
problems around the ##any types it defines, the reported errors are:

saml-schema-protocol-2.0.xsd:50:56: error: element 'Signature' is 
defined here
saml-schema-protocol-2.0.xsd:229:81: error: such wildcards are not supported
saml-schema-protocol-2.0.xsd:229:81: error: namespace '##any' allows for 
element 'Extensions'
saml-schema-protocol-2.0.xsd:51:60: error: element 'Extensions' is 
defined here
saml-schema-protocol-2.0.xsd:229:81: error: such wildcards are not supported
saml-schema-protocol-2.0.xsd:229:81: error: namespace '##any' allows for 
element 'Status'
saml-schema-protocol-2.0.xsd:52:42: error: element 'Status' is defined here
saml-schema-protocol-2.0.xsd:229:81: error: such wildcards are not supported

The schema is available from:
http://docs.oasis-open.org/security/saml/v2.0/saml-schema-protocol-2.0.xsd

The corresponding piece of schema is:

    <element name="ArtifactResponse" type="samlp:ArtifactResponseType"/>
    <complexType name="ArtifactResponseType">
    	<complexContent>
            <extension base="samlp:StatusResponseType">
                <sequence>
                    <any namespace="##any" processContents="lax" minOccurs="0"/>
                </sequence>
            </extension>
    	</complexContent>
    </complexType>


Command:
./xsd cxx-tree --show-sloc --generate-polymorphic --namespace-map 
http://www.w3.org/2001/04/xmlenc#=w3::xmlenc --namespace-map 
http://www.w3.org/2000/09/xmldsig#=w3::xmldsig --namespace-map 
urn:oasis:names:tc:SAML:2.0:assertion=saml::assertion --namespace-map 
urn:oasis:names:tc:SAML:2.0:metadata=saml::metadata --namespace-map 
urn:oasis:names:tc:SAML:2.0:protocol=saml::protocol --output-dir.........

There is another instance of ##any in the same schema file which seems 
to pass by without problem, I have looked at the various pieces of 
documentation and can't seem to determine if there is any specific flag 
I should be setting to get this to operate correctly. Can anyone please 
advise if XSD should be able to compile this schema and if so what I 
might be doing wrong? The "such wildcards are not supported" statement 
is a bit of a concern.

thanks,
Bradley
