| org.w3c.dom.DocumentType | 
Each Document has a doctype attribute whose value
 is either null or a DocumentType object. The
 DocumentType interface in the DOM Core provides an interface
 to the list of entities that are defined for the document, and little
 else because the effect of namespaces and the various XML schema efforts
 on DTD representation are not clearly understood as of this writing.
 
DOM Level 3 doesn't support editing DocumentType nodes.
 DocumentType nodes are read-only.
 
See also the Document Object Model (DOM) Level 3 Core Specification.

A NamedNodeMap containing the general entities, both
 external and internal, declared in the DTD. Parameter entities are
 not contained. Duplicates are discarded. For example in:
 
<!DOCTYPE ex SYSTEM "ex.dtd" [ <!ENTITY foo "foo"> <!ENTITY bar "bar"> <!ENTITY bar "bar2"> <!ENTITY % baz "baz"> ]> <ex/>the interface provides access to
foo
 and the first declaration of bar but not the second
 declaration of bar or baz. Every node in
 this map also implements the Entity interface.
 entities cannot be altered in any way.
The internal subset as a string, or null if there is none.
 This is does not contain the delimiting square brackets.
 
Note: The actual content returned depends on how much information is available to the implementation. This may vary depending on various parameters, including the XML processor used to build the document.
The name of DTD; i.e., the name immediately following the
 DOCTYPE keyword.
A NamedNodeMap containing the notations declared in the
 DTD. Duplicates are discarded. Every node in this map also implements
 the Notation interface.
 
The DOM Level 2 does not support editing notations, therefore
 notations cannot be altered in any way.
The public identifier of the external subset.
The system identifier of the external subset. This may be an absolute URI or not.
