Embedding html in XML

Question,

	if I need to include some text formatting inside XML elements.  What's the
best what to do it.  I'm using the MSXML parser and it seems to be ignoring
any html within the XML.

EXAMPLE

<someXMLdata><font class="header">T</font>he first letter is
bold</someXMLdata>
<someXMLdata><font class="header">The whole sentence is
bold</font></someXMLdata>
<someXMLdata><p>The whole sentence is it's own paragraph</p></someXMLdata>

When I parse the file and display it, it takes out the embedded html text to
format the text . Is this normal?

Thanks
Kris
