  I was thinking more of the general case, DOM or otherwise.  I think
it would be really nice to have this sort of proxy available in a
"high performance" implementation.  The reality is that several
variants might be needed (with various support for mappings,
sequences, etc.), but that's a detail symptomatic of the type/class
dichotomy and not a long-term issue.  It may not be realistic to share 
one implementation, and may not be worth the C code if not.
  But to support "sharable sub-hierarchies" as Ken described, we would 
need to use some sort of proxy solution.
