You're right. I've been so brainwashed by our use of CORBA on our
project that I forget that you can do that kind of thing. That would
certainly satisfy the requirement I have.

But I think that this is probably a requirement against the DOM spec
itself--that is, the notion of preserving the data source for DOMs is, I
think, a general requirement that all DOM implementations should
satisfy.

Cheers,
