Actually, I am using it in a linear-processing model (you must view
this with a monospaced font like Courier):

* David's Model:

  PARSER --> SAX-J --> DOM --> [tree-based user application]
               --------------> [event-based user application]

In other words, a DOM builder would be just another an event-based
SAX-J application.

In this case, I am using a slightly different model:

* Tim's Model:

  PARSER --> DOM --> SAX-J --> [event-based user application]
              ---------------> [tree-based user application]

In other words, SAX-J would be just a simpler event-based API for the

I don't see a very pressing need for the latter -- tree structures are
familiar to coders, whether or not know anything about XML -- but I
would be happy to implement it if requested (I do not want to exclude
PI's, however, since that will exclude the possiblity of using
architectural forms and other standards working on top of XML).

Is this what everyone else is expecting?

All the best,
