Many of us will be authoring documents where the 'root' is almost
meaningless. It is highly probable that many 'CML' documents will have a
root element of <HTML:HTML>. Example:
<?xml:namespace ns="http://w3.org/some/where/html" prefix="H"?>
<?xml:namespace ns="http://xml-cml.org/cml" prefix="C"?>
<H:HTML>
<H:HEAD>... </H:HEAD>
<H:Body>
<H:P>
<H:UL>
<H:LI>
<C:MOL title="benzene">...</C:MOL>
</H:LI>
<H:LI>
<C:MOL title="toluene">...</C:MOL>
</H:LI>
<H:LI>
<C:MOL title="ortho-xylene">...</C:MOL>
</H:LI>
</H:UL>
</H:P>
</H:BODY>
</H:HTML>
The fact that this document uses H:HTML as its 'root' is virtually
irrelevant to its semantic message.
