The alltests could be generated from a directory using Ant.  However, 
the original idea behind the test suite definitions was that tests would 
go through a review cycle and there could be tests in the directory that 
were submitted but not accepted.  alltests was going to contain all 
tests regardless of status and there would be other suites of accepted, 
provisional and rejected tests, however that never evolved.  The 
downside of moving a test to signify rejection was that any test results 
that used that URL would be broken.

I think I would prefer a more declarative approach, maybe an array 
containing with elements like:

tests[tests.length] = { 			 
"characterdatainsertdatanomodificationallowederr",   // test name
	null,                       // content type
	{ "XML" }, { null },        // features name and versions
	{ "expandEntityReferences" }, { false } };  // impl attributes

The function suite() method could iterate through the array and add only 
the applicable tests to the suite.

The Java framework does not give any indication that non-applicable 
tests are omitted.  If you want to avoid the situation of a processor 
passing, for example, the L3 Load Save suite because it passed 0 of 0 
tests by return false to hasFeature("LS-Load", null), you can always 
have one unguarded test that checks the feature.  I think that listing 
page after page of inappropriate tests could be distracting.

I'll also application/xhtml+xml to the contentType enumeration in the 
schemas and DTDs.

I avoided dynamically created the IFRAME's since I thought it was one 
less moving part and the cost of an unused IFRAME was negligable.

When I migrated the previous code to JSUnit 1.3.3, I retrogressed in 
functionality and temporarily dropped support for the other loaders, but 
I expected to reimplement additional loaders as we added back 
functionality.  I prefer the loader classes over extensive use of switch 
statements to achieve the same thing.

For XML processors, they are essentially redundant with the non hc_ (for 
HTML compatible) tests.  However, without them there is minimal coverage 
of L1 core behavior for HTML processors.
