It is impossible to specify in a DTD that CDATA sections are used, just
as it is impossible to say that you have to use " rather than ' around
attribute values. CDATA sections are just part of the lexical syntax
layer: a DTD validator does not see if they are used or not, just as XSLT
does not see if they are used.


If <x><![CDATA[abcde]]></x> is DTD valid, then so is <x>abcde</x> as it
is identical input.
