I have put the following up on my personal home page temporarily, eventually
these will be hosted on xmlconf.sourceforge.net

The "complexity" has to be somewhere, by putting it in the schema or DTD, it
enables schema or DTD-aware editors to guide the user in building the test.
If you just used generic <CALL> elements, then the user is going to have to
guess the supported method names and find their errors when they try to
compile their Java code after doing an XSLT transform.

I designed the schema based on my experience with migrating the NIST DOM
tests to the JUnit, JSUnit, and CppUnit frameworks.  I definitely believe
that it is much more friendly to generating xUnit code than anything else
proposed.

Link to a generated DTD appears above.  Using only a DTD aware editor will
not check, for instance, that the index argument to the NodeList.item method
is either an integer literal or a variable reference, but it will enforce
all the structural constraints.

It is definitely possible to place RDF and Dublin Core metadata within the
test element.  For example, SVG defines a metadata <element> for exactly
this purpose.  However, you can't keep all the evolving metadata about the
test within the test definition and since you can't keep all of it there,
why keep any of it there.  It would definitely be fairly straight forward to
write XSLT that ensures that all tests defined in the test definition have
at least minimal metadata in the base RDF file.
