To prevent problems with embedded characters, surround your content with CDATA sections.

A CDATA section starts with:

 <![CDATA[ 

A CDATA section ends with:

 ]]>

You can embed any combination of tags, special characters, and text in a CDATA section, 
and your XML processor will treat it as text. One rare exception is when you want to embed a 
CDATA close (]]&gt;) within a CDATA section. In this case, use ]]&amp;gt;.
