the xml parser with cl-http signals exceptions. lisp's control model permits
the handler to execute in the dynamic context of the parser which would permit
the caller to decide what to do. on the other hand, i've yet to implement any
continuations: i terminate the parser, but other options are possible.

one intrinsic problem with java parsers is that the java control model forces
exceptions to unwind from the initiator's dynamic  context before the handler
obtains control. this would mean that a callback interface would have to be
proposed, ratified, and implemented. i recall discussions of such a thing when
sax started, but the recollection is vague.
