new : 
        name:string *
        publicId:string *
        systemId:string *
        internalSubset:string -> XDocumentType


Type: System.String

A String that contains the qualified name of the DTD, which is the same as the qualified name of the root element of the XML document.

Type: System.String

A String that contains the public identifier of an external public DTD.

Type: System.String

A String that contains the system identifier of an external private DTD.

Type: System.String

A String that contains the internal subset for an internal DTD.

The following example creates a document with an internal DTD. When it creates the XDocumentType object, it specifies the qualified name of the DTD (Pubs), and a string that contains the internal subset. Because the document does not use a public or private external DTD, the publicId and systemId are set to null.

No code example is currently available or this language may not be supported.

This example produces the following output:
