XML DTD

An XML document type declaration (DTD) is represented by a syntax element of type DocTypeDecl and its children and descendants. These comprise the DOCTYPE construct.

Only internal DTD subsets are represented in the syntax element tree. External DTD subsets identified by the SystemID or PublicId elements can be referenced in the message but the broker does not resolve those references.
