No, but at some point there will be.

No.  The normalised value is "a b", and that matches production 8.

Erratum 8 clarifies that the validity constraints are applied after
normalisation.

Right.  I think the spec should be changed to require that the
normalised value match a production with #x20 instead of S.  Otherwise
the normalisation doesn't have the obviously (!) intended effect of
passing the application a string of tokens separated by spaces.  And
in any case I believe this change is required for SGML compatibility.
