You're confusing document conformance requirements and UA conformance  
requirements. The content model applies to documents. The later text you  
referred to applies to UAs. (UAs need to handle non-compliant content.)

The Conformance requirements section has the following note:

| Note: There is no implied relationship between document conformance
| requirements and implementation conformance requirements. User agents are
| not free to handle non-conformant documents as they please; the
| processing model described in this specification applies to
| implementations regardless of the conformity of the input documents.
