Well-formedness, I think. "Validation" when speaking of XML typically
refers to verifying that the well-formed XML document matches the
production(s) found in some schema language file, of which the best
known are DTD (the original, included in the 1.0 spec), W3C XML Schema,
and Relax NG, but there are other forms that supply different rules for
content validation not based on grammars (Schematron most notably). All
of them operate over well-formed XML and it's well-formedness that
marks the boundary between "XML" and "some mess of pointy brackets and
nonsense that can't be successfully parsed".

It is practically impossible to teach good programming to students that

mentally mutilated beyond hope of regeneration.
