Right now the spec requires that you use id="", but both name="" and 
id="" work, and they are case-insensitive. So we have back-compat (except 
in esoteric cases where pages expect it _not_ to match something, or where 
there are duplicates). Is that ok?

The case-insensitiveness on ID could be a problem. Should that change?
