I agree that for ECMA to give its stamp of approval, whatever form
that might take, causes extra complications.  But I don't know why should be so closely linked with ECMA that we can't use
it for this.  Isn't it up to us, Brendan really, to decide how to use

I think it's important that this is and is perceived as, now and in
the long run, a vendor neutral project.  If we host it with vendor A,
for any choice of A including google, it's much too easy for people to
consider it A's project, and in particularly for other vendors to not
consider it theirs.

I've been using the ES5 layout tests myself and they are indeed very
thorough.  Having them be part of the common test suite would be
