No, this applies to all parameter entities; it is our belief that
parameter entities are included in XML only for the purpose of 
supporting DTD construction, i.e. validation; thus if you're not
validating, they are not useful.  Furthermore, PEs are kind of
ugly and baroque in their design, and represent an unreasonable
workload for a lightweight on-the-client processor.

Your example must always produce the result "hello"... check the
last sentence of section 5.1

<!DOCTYPE foo [
    <! ENTITY % ent1 "&#60! ENTITY hi 'hello'> ">
    <! ENTITY hi "bye">
