The sentence you are looking for in the standard occurs in section
4.3.2:

  All internal parameter entities are well-formed by definition.

As you gathered, you need the trailing space after !<ELEMENT above,
since parameter entities are included literally when used in entity
values (that is, they don't get padded with spaces).

If you run the following text through a validator, the only error
you'll see says that you're using parameter entities more liberally
than the XML standard allows for the internal DTD subset:

<!DOCTYPE Bubba [
  <!ENTITY % Part1 "<!ELEMENT ">
  <!ENTITY % Part2 " Bubba ANY>">
  <!ENTITY % Whole "%Part1;%Part2;">
  %Whole;
]>
<Bubba></Bubba>
