DocumentInformationItem Class

The DocumentInformationItem class represents an XML document and exposes the properties

of the Document Information Item as well

as the post-schema-validation infoset properties for the validation root.

There is exactly one DocumentInformationItem in the information set, and all other InformationItem objects

are accessible from the properties of the DocumentInformationItem, either directly or indirectly

through the properties of other InformationItem objects.
