Bad entity usage?

Help - I cannot make out what is wrong with this entity usage:

<?xml version="1.0"?>

<!ENTITY % AB "(A|B)">

<!ATTLIST D Att %AB; "A">



Microsoft IE5 gives an error:
"Parameter entities cannot be used inside markup declarations in an
internal subset."

Is this true? I cannot find any such rule in the XML Rec standard. IE5
is happy if
I do it in an external DTD.

I would be grateful for any light on this.
