# FIXME:
# * Import more tests rather than just the very limited set currently
# chosen.
# * Read in a (checked-in) input file with a list of test assertions
# expected to fail.
# * Read in a (checked-in) input file with a list of reference choices
# for tests with multiple rel="match" references. (But still go
# though all those references in case they, in turn, have references.)
# Eventually we should import all the tests that have references. (At
# least for a subset of secs. And we probably want to organize the
# directory structure by spec to avoid constant file moves when files
# move in the W3C repository. And we probably also want to import each
# test only once, even if it covers more than one spec.)
# But for now, let's just import a few sets of tests.
