T5 : Jira TAP5-290 not entirely resolved

[Stephane Decleire]

The correction linked to Jira TAP5-290 defines the namespaces as needed 
but the tag generated is not the same in a full and in a partial render :

In my sample, the <div> tag printed during a full page rendering :
<div class="msg">
   <div>...</div>
</div>

becomes an <ns0> tag :

<ns0:div class="msg" xmlns:ns0="http://www.w3.org/1999/xhtml"; xmlns:ns1="">
   <div>...</div>
</ns0:div>

and my class="msg" css information is no more applied.
