<![CDATA is just a syntactic alternative to using &lt; and &amp;
It just makes all occurrences of < and & within its scope be
automatically taken as character data rather than markup (it _only_
affects these two characters).

> so this isn't java. (&lt;)

It is, as encoded in XML.
The character data in the XML consists of a single < character, if you
extract the text from a DOM, or for example look at string-length() in
Xpath, you will see that there is a single < character there, it is just
that the way to write a single < character in XML is &lt;.

Any application that extracts the text from the XMl file and passes it
to a program interpreter should pass the actual character data, not its
XML encoding, so java(script) will never see the &lt;.

this is exactly the same as in Xpath: the Xpath test is 1 < 2 but if you
use XPath in an XML context, you need eg <xsl:if test="1 &lt; 2">
The XPath interpretter is not confused by the entity reference as that
has been expanded by the XML parser before the Xpath system ever sees
the expression.

If you are producing html, then any < or & signs appearing as content of
a script element should appear in the result as < or & (even though they
are entered using &lt; and &amp;, or equivalently, <![CDATA).
