I'm not even sure this is the whole story.  Section 3.3.3 Attribute-Value 
Normalization, of the XML 1.0 (Third Edition) says,

    Before the value of an attribute is passed to the application or checked 
    validity, the XML processor MUST normalize the attribute value...

So I think IDREFS only needs to match Names after normalization.

I've always assumed that the lexical space is pre-normalization, but I can't 
at the moment find anything that tells me this either way.
