No, the XML 1.0 spec declares that non-whitespace control characters (with or without the eighth bit set) are illegal in XML and entities for illegal characters are illegal.

I don't know it CDATA removes this restriction. I'd think it would but after being surprised by the control-character stupidity and seeing many XML near-experts also boggled by it, I won't speculate w/o reading the spec first.

Of course, if you prefer the attribute-heavy style of XML, then CDATA won't be any help (I say w/o verifying this assumption but I'd nearly bet money on it).

I feel PerlMonks' XML should be nearly or completely attribute-free. But that isn't much help since we already have a heavy base of ticker clients that don't handle CDATA.

So when I said that control characters are a problem, I wasn't so XML-naive as to not have considered entities and CDATA.
