Yes.

That does not mean that *every* literal is capable of being used to
specify a well-formed internal entity declaration.  The restriction of
matching the content production is superadded to the definition of a
literal.

There are occasional anomalies of this sort, which are of no consequence.
When fooling around with "]]>", always use "]]&gt;" instead -- it was
for this reason that &gt; was provided in XML.

If you think it's a problem, mail it to xml-editor@w... .
