   Re: [xml-dev] Embed an XML document in another XML document

Enclosing CDATA sections within CDATA sections just requires breaking 
each enclosed CDEnd into two parts. Say the original document has:

<?xml version="1.0" encoding="UTF-8"?>
<foo><![CDATA[if (a<b)]]></foo>

The CDATA enclosed document is:

<body><![CDATA[<?xml version="1.0" encoding="UTF-8"?>
<foo><![CDATA[if (a<b)]]]>]><![CDATA[</foo>]]></body>

A bit tedious, like all escaping, but a program can (un)do it.
