The W3C "Particle Valid (Restriction)" MapAndSum rule (XSD 1.0 §3.9.6): a derived
sequence restricting a base choice is valid iff each derived particle restricts
some base branch AND the derived sequence's occurrence count times its number of
particles lies within the base choice's occurrence range.
PureXML applied the same-compositor occurrence subsumption (the sequence's own
range against the choice's), which both rejected a valid restriction
(sequence{2,4}(e1,e2) of choice{3,9}(e1,e2): 4..8 elements fit 3..9) and accepted
an invalid one (a two-member sequence restricting a single-occurrence choice,
count-product 2 > 1). The count-product is the spec's measure, matched to the
reference implementation (checkMapAndSum/checkOccurrenceRange).
The (sequence, choice) branch in groupValid is retained: it is reached by the
(element, group) RecurseAsIfGroup path, which wraps an element as a one-particle
sequence against a base choice.
XSTS: valid schemas rejected 2 to 1, invalid schemas accepted 520 to 519, no
other bucket raised. The remaining valid-rejected case (particlesZ001) is a
documented spec ambiguity (RecurseAsIfGroup), recorded in docs/xsts-deviations.md.
