The change is in fact a subtle one: it affects only the *value* of an attribute,
which is what you have after the attribute-normalization process described
in clause 3.3.3 is performed.  (Note that 3.3.3 has been clarified by E24 and E61.)

Consequently, although

	<element magic="foo

where "magic" is of type ENTITIES, IDREFS, or NMTOKENS, will still work (and return
a value of "foo bar"), under E62 it is invalid to say:

	<element magic="foo&#10;&#9;&#9;&#9;bar"/>

Of course it is still well-formed.

Does anyone seriously think that the second example ought to be valid?
