Mihaela Mihaljevic 87cc83d0ce fix(schema): stop Particle Valid (Restriction) over-rejecting valid schemas
The restriction subset check rejected 72 valid schemas (#148). Three
language-preserving corrections:

- Remove pointless particles (maxOccurs=0) from both the derived and base
  content before mapping, so they no longer consume a base particle and starve
  the particles after them (e.g. (e1 maxOccurs=0, e2) restricting (any)).
- A content-free restriction (an empty sequence, or a group whose members all
  cannot occur) is a valid restriction of an EMPTY base: both accept only the
  empty sequence.
- A derived group that reduces to empty after that removal validly restricts its
  base only when the base is itself emptiable (emptiable(base) accounts for the
  base's own occurrence), closing the vacuous-acceptance gap the removal would
  otherwise open in the MapAndSum and choice paths.

XSTS: valid schemas rejected 72 to 45. invalid schemas accepted 527 to 528 from
addB32, whose only invalidity is a malformed imported document not yet loaded
(#161); the restriction itself is valid, so accepting it is correct.
