Some questions about XML 1.0

After reading the XML 1.0 spec, a few questions remain.

Is it legal to have a reference to an external parameter entity inside
an EntityValue?
E.g:
<!ENTITY % somePe SYSTEM "foobar.ent">
<!ENTITY someEntity "a %somePe; b">

Should parameter entity references be recognized and expanded in
AttValues inside the DTD (i.e. in [60] DefaultDecl)?
E.g:
<!ATTLIST elem attr CDATA "a %somePe; b">

Best Regards
Mikael
