I think you can.  I think I gave something close to a real
way of doing it which would actually be bc with css1 browsers.

Nice rhetoric.  Most of these bits (not all) don't matter much
except that you'll get some bad formatting.  That's different from
really wrong things happening,  which is my suspicion for the extension
syntax for selecting on child/sibling information.

All good standards work *must*, not may, pay attention to what the real
implementations are doing.  Turning a blind eye is not an acceptable
response.  Why not critique the idea of using the pseudo-class/element
syntax instead of attacking the browser makers?  And *if* there's such a
way to do this,  why not do it that way?

I notice BTW that nobody has even bothered commenting on the clash
between this work and DSSSL/XSL.
