OK I think I'm seeing what you are seeing now.  3.3.3 specifies behavior for
BOTH Character References and Entity References.  Elsewhere in the Rec a
clear distinction is made between character references and entities. The
Character Reference behavior is just to append, not to do any recursive
normalizing.  But the paragraph on replacing spaces with a single space only
applies to #x20 spaces, not to any other kind of whitespace
So the tab wouldn't get removed, as you say.

I wonder if this was an error or intended?  The text in the Rec is

"If the declared value is not CDATA, then the XML processor must further
process the normalized attribute value by discarding any leading and
trailing space (#x20) characters, and by replacing sequences of space (#x20)
characters by a single space (#x20) character."

Maybe they intended "...sequences of whitespace..." instead.

Anyone know for sure which way this was supposed to read?
