The test is wrong.  Some people have interpreted the table in section
4.4 as saying that parameter entities are recognised in attribute
defaults, but this is fixed in erratum 41
(http://www.w3.org/XML/xml-19980210-errata#E41):

 Section 4.4

   Change the definition corresponding to "Reference in DTD" to read:
   "as a reference within either the internal or external subsets of
   the DTD, but outside of an EntityValue, AttValue, PI, Comment,
   SystemLiteral or PubidLiteral." (with suitable links).

The test does not match the spec, and I have asked for clarification
(by mailing the xml-editor address given in the spec).  I believe that
the answer *should* be that the normalised result is "a\nb" and that
this should be invalid (but well-formed).  It's invalid in SGML
because the result of expanding a character entity is treated as
character data and not as SPACE.

No.

Did you find an Oasis test that gets this wrong?

Looking at the spec, it appears not.  This seems a little surprising
to me, since content models usually only restrict element and text
content.
