This is going to get worse. Perhaps we should use:
well-formed: as defined in XML 1.0 (loosely, matching tags
etc)
valid: as defined in XML 1.0 (loosely, conforms to its own
DTD)
conforms to XYZ: conforms to the rules of standard XYZ (e.g.
XML-Namespace). This may of course be an
application-oriented (anti-barfing) standard
obeys ABC: conforms to the constraints specified in XSchema
ABC
These are predicates that can be applied to any XML document
including, of course, an XSchema. For an XSchema [document]
to be conformant to the XSchema standard if must be
well-formed, it must be valid under the XSchema DTD, and it
must meet additional constraints described in the text of
the XSchema standard.
An interesting question: is it an objective to allow all
[reasonable] "conformance" rules for an application to be
expressed as XSchema constraints?
