Superclass of all conditions signalled by the CXML parser.

<p>
<div class="def">Condition class CXML:WELL-FORMEDNESS-VIOLATION (cxml:xml-parse-error)</div>
This condition is signalled for all well-formedness violations.
(Note that, when parsing document that is not well-formed in validating
mode, the parser might encounter validity errors before detecting
well-formedness problems, so also be prepared for <tt>validity-error</tt>
in that situation.)

<div class="def">Condition class CXML:VALIDITY-ERROR (cxml:xml-parse-error)</div>
Reports the violation of a validity constraint.
