Properties

publicId: The public identifier of the external subset.
systemId: The system identifier of the external subset. This may be an absoluteURI or not.
name: The name of DTD; i.e., the name immediately following theDOCTYPE keyword.
entities: A DOMNamedNodeMap containing the general entities, both external and internal, declared in theDTD.
notations: A DOMNamedNodeMap containing the notations declared in theDTD.
internalSubset: The internal subset as a string, ornull if there is none. This does not contain the delimiting square brackets.
