It is the opinion of two test suite Peers, L. David Baron and Anne van Kesteren,
that David Baron's suggestion to rely on the normative error handling rules as
above is sufficient to test that the invalid selector [1badAttr] is correctly
ignored. Arron Eicholz disagrees. The vote tally is 2 vs. 1 and the thread's at
a standstill.

It is my opinion as the test suite Owner, that David Baron's suggested test is
sufficient to test the assertion "Attribute values cannot begin with numerals."
If Arron wishes he can escalate the issue to the Working Group. Otherwise this
discussion ends here and the test must be revised as indicated before being
accepted into the W3C test suite.
