As I understand it, <foo:bar/> is an XML well-formed document, but is not an 
XML Namespace well-formed document.  Just because it isn't namespace 
well-formed shouldn't mean it shouldn't be successfully parsed as an XML 
well-formed document.  There was some discussion on this on the libxml2 
mailing list a while back (you might have to look at earlier mails in the 
thread to get the context):

    http://mail.gnome.org/archives/xml/2011-March/msg00022.html

Therefore I think it's at least suspect to treat <foo:bar/> as <bar 
xmlns='foo'/>.  Whether civilisation as we know it would fall apart if you 
do I don't know!

So rather than doing:

    <com.foo:bar/>

I would suggest doing:

    <:com.foo:bar/>

This is XML well-formed, but the initial colon means that it is not XML 
namespace well-formed.  You could claim that it was XML namespace-bis 
well-formed though.
