Note, this won't help Xslt much with Stylesheets as they need to inherit
from a class (cDomlette won't work).  2.2 let's us get around that but I
don't think we want to inforce 2.2 yet.

I have been thinking of breaking the Stylesheet -> pDomlette dependency
by putting (another) little DOM in Xslt that is for stylesheets only. 
we only need a handfull of elements on Element, and Text Nodes.  Would
be pretty small in size.
