Not sure its applicable.

I write a blog using atom, xhtml in atom to be precise.

To validate it I use the atom rng schema and
a mod to the xhtml schema (since I root the xhtml in div I
added div as a start candidate.)

<rules xmlns="http://purl.oclc.org/dsdl/nvdl/ns/structure/1.0";
   xmlns:a="http://www.w3.org/2005/Atom"; 
xmlns:x="http://www.w3.org/1999/xhtml";
   startMode="doc"   >

   <mode name="doc">
       <namespace ns="http://www.w3.org/2005/Atom";>
           <validate schema="atom.rng">
               <context path="feed/entry/content" useMode="xhtml"/>
           </validate>
       </namespace>
   </mode>


   <mode name="xhtml">
       <namespace ns="http://www.w3.org/1999/xhtml";>
           <attach/>
           <validate schema="xhtmldiv.rng" />
       </namespace>
   </mode>
</rules>


then
<grammar  xmlns="http://relaxng.org/ns/structure/1.0";>
<include href="xhtml.rng">
<start combine="choice">
   <ref name="div"/>
</start>
</include>
</grammar>

xhtml.rng is a standard xhtml schema in rng.


That seems to work for me.
I catch most of my sillies this way..
