I apologize for my lateness in replying.
Internet Explorer has an ECMAScript implementation that does not support
exceptions, per se.  We return error codes from the scripting engine.

I have a lot of not fully realized thoughts on this topic and it is more
complicated than it appears.  However, I can't go into it right now.  I
think that we can have this covered.
Jason can you outline the particular DOM and ECMAScript implementations
that you are concerned with supporting?  Particularly which of the
ECMAScript implementations do not support exceptions and what mechanism,
if any, is there to detect the error conditions raised from DOM

	We have not yet looked at allowing the new 
	jsunit-based harness to discriminately run 
	tests -- it currently runs all available tests at 
	once and provides a report.  Have you tried 
	to run this yet Jason?  I'd be interested in 
	your reaction.  We do, however, have the 
	ability to insert inside a particular test that it 
	will only run with a particular module -- we have 
	not yet done this -- but I would think that doing 
	so would cover the HTML-only tests.  Maybe 
	Curt can comment on how we should use 
	this feature, and what the transform does 
	with this information.

		Hi Dimitris,
		My comment could take on several meanings, depending on
the design of
		the test harness.  Originally, I meant that there should
be an option to
		only run the tests that match the capabilities of the
client in
		reference to HTML-only implementations and
implementations that do not
		support exceptions.  This is consistent with discussions
that took place
		early on in the development of this test suite.  I'm not
proposing any
		modularization other than that.
		Depending on the implementation of the harness, we could
also provide
		ways of running only certain portions of the test suite,
based on the
		needs of the user.  The current NIST harness provides
some basic
		functionality by using a SELECT control to specify the
"DOM Category"
		and another SELECT control to specify the "DOM
Interface."  The test
		case selection process could be made better.  I've
attached a *sample*
		of what this could look like.  (THIS IS ONLY A MOCK-UP!)
In addition,
		running the suite would be automated, or at least take
less time for a
		person to run the conformance suite.
		Flexibility in test case selection would lead to more
useful reporting.
		Users would only get back the information they desire
instead of sorting
		through test case areas that don't concern them.  Also,
the results
		would be posted on a single HTML page (or XML file?)
instead of
		requiring the tester to visit each interface, record the
results, and
		move on to the next interface.

		Hi Jason
		Please provide a more detailed account of what this
would mean; running 
		different parts of the test suite? Have different test
suites built to 
		begin with in accordance with existing browser
capabilities? Currently 
		we haven't limited the suite in any other way than
defined by the DOM 
		specification, except for entity exapansion and
whitespace preservation 
		in parsers.
		In order to come to an understanding about the harness
thus: how should 
		we act in this matter? Should we modularize the test
suite in some way? 
		We have discussed this in the past, and given the fact
that we want to 
		release the test suite as soon as possible it seems a
good idea to make 
		this explicit very soon.
		In our previous discussion though, we decided to go for
using a 
		modularization that stayed as close as possible to the
		specification. On the other hand, we obviously want to
be able to run 
		the test suite in all major browsers. IE can be tested
running the Ecma 
		tests with the JSunit framework by running ant
dom1-core-gen-jsunit to 
		build the appropriate code.
