Sameer,

=BB   Luis,
=BB  =20
=BB   ALL_TAG is not a subclass of ExprTag, so it cannot be used=20
=BB   inside SetTags or SimpleTags.  My mistake -- the example I=20
=BB   gave earlier won't work:
=BB   ("p" (*) "/a/b/c/d") // illegal!
=BB  =20
=BB   Perhaps this is something that should be changed about the=20
=BB   SPKI spec, but for now, the only way to grant all=20
=BB   permissions inside a simple tag is to list the all out:
=BB   ("p" (*set permission1 permission2 permission3) "/a/b/c/d")
=BB  =20
=BB   Good catch,
