]]> is used to close CDATA sections.
When there _isn't_ any CDATA section,
there's no good reason for ]]> to be reserved.
It just is.
As it happens, I know very well, as my messages have made clear,
that ]]> is reserved; but since there is no obvious reason why
it should be, and since it is a pretty rare sequence, other
people aren't always aware of that.
And they should never have had to be.

By the way, when I try that example xmllint, I get
-:1: parser error : internal error: detected an error in element content
-:1: parser error : Extra content at the end of the document
(o)nsgmls also warns about this, but as I wrote,
the parsers I normally use -- as they are much faster --
happen to be silent about this.
