Unless the string contains "]]>" of course.

There is no way to avoid escaping arbitrary strings included in XML documents.

Through the life of this thread I've completely lost track of what
LuaSoap actually does for me. As of 3.0 it appears it will correctly
marshal LOM into XML; what else is needed?

CDATA is just another escape mechanism. The choice between it and
&lt/&amp escaping is a matter of coding efficiency. CDATA has higher
overhead but after the third escaped entity it's more
efficient--unless your text has many more "]]>" sequences than "<" and
"&". This is the kind of thing a good XML library should handle for
me: getting this right once, so I just don't naively strsub every time
I need output. A heuristic of "use CDATA if the string starts with '<'
and is longer than ten characters" is a good start, as is a population
count of [&<] of the first hundred characters.

There are a couple other things I want in an XML output library,
starting with...UTF-8 validity, and barring invalid codepoints.
