Re: External parsed entities under SaxonJS

It would be nice if they at least supported an internal DTD and internal entities.

And there's no real reason for any restrictions on Node.js, other than the fact that parsing DTDs is a crazy amount of effort in relation to the number of people who actually use them, because of the arcane syntax and the wierd rules surrounding parameter entities.

I've wondered about extending the parser we use on Node.js with an "entitty reference resolver" whereby entity references are resolved by a callback to a user-supplied function -- which I suspect would be far more useful to far more people than putting the expansions in a DTD.
