valid xml document造句

IRP protocol messages are valid XML documents.
The PSVI gives a valid XML document its " type " and facilitates treating the document as an object, using object-oriented programming ( OOP ) paradigms.
A valid XML document is defined in the XML specification as a well-formed XML document which also conforms to the rules of a Document Type Definition ( DTD ).
Sometimes the adjective "'well-formed "'is used to contrast with "'valid "': a valid XML document is one that is not only well-formed, but also conforms to the grammar defined in its own DTD ( Document Type Definition ).
