It may be the case that currently popular browsers do that, but it surely can't
be the case that _no_ html implementation parses html4 attributes as specified
by html4? Certainly any sgml based validators won't do that, and can you really
be sure that no existing  html editors for example, assume that attributes are 
parsed by HTML4 rules which would normalise white space?

And given that major browsers currently are very inconsistent in using the
result of the title attribute parse, compatibility with existing bugs doesn't
seem a particularly strong argument for introducing a new attribute parsing
rule at this point, incompatible with xml and html4, especially when the user
experience of the new behaviour is likely to be sufficiently bad that it's
thought necessary to add a warning about it to the spec.
