Because it would be redundant. If the XML header says what characters are
available then the editor can directly enforce that constraint.

Overloading markup in this way is, in my opinion, a bad idea. It can do
nothing but bring harm in the long term because no two applications will
agree on the overloaded semantics and thus no two applications will treat
the data in the same way.

This would eliminate the most interesting thing about CDATA sections:
character suppression. Making <![JAVA[ RCDATA is going in the wrong
direction. Rather it should be a CDATA-on-steriods that even ignores CDEnd
("]]>") and only looks for something like ]JAVA]> to end the section.
