1.4.3. "Valid" XML documents
"Valid" XML documents
An XML document has to be
checked not only for its wellformedness but also for its validation. We already
presented you the wellformedness of an XML document in the former chapter. Just
to remind you: A "well formed" XML document is a document that
conforms to the XML syntax.
A "valid" XML document
however is a "well formed" XML document, which also conforms
to the rules of a DTD or an XML Schema.
