Enforce the two occurrence-range constraints on model groups that PureXML
was not checking:
- p-props-correct.1: a particle's minOccurs may not exceed its maxOccurs,
both defaulting to 1 when the attribute is absent. occurrenceOrderErrors
previously fired only when BOTH attributes were present, so it missed
minOccurs="2" with a defaulted maxOccurs (2 > 1) and maxOccurs="0" with a
defaulted minOccurs (1 > 0). It now orders against the effective defaults.
- cos-all-limited.2: an all group's maxOccurs must be 1 and its minOccurs
0 or 1, and every particle it contains is limited to maxOccurs 0 or 1.
Both are zero-false-positive rules (no valid schema violates them). XSTS:
invalid-schemas-accepted 130 to 110 (20 caught), valid-schemas-rejected
held at 0, no other bucket moved. The differential harness corroborates:
agree-invalid 1751 to 1767, PureXML-stricter unchanged at 87 (no new
over-rejection across 9618 schemas).
