Mihaela Mihaljevic a09e68b6fa fix(schema): a content-bearing derived group cannot restrict a base element ... XSD 1.0 §3.9.6 Particle Valid (Restriction) defines a case for an element restricting a base group (RecurseAsIfGroup) but none for the reverse, so a derived sequence/choice/all that can contribute a child never validly restricts a single base element. The oracle had a deliberate non-spec 'mirror' extension that bounded the derived group by the element's effective occurrence range and accepted it; that masked a real violation inside a choice-to-choice restriction, where a derived sequence branch was allowed to map onto a base element branch it cannot legally restrict. The (.group, .element) case now returns invalid; a content-free derived group is still a valid restriction of any emptiable base (handled before this case). Catches particlesHb011. XSTS invalid-schemas- accepted 17 to 16, valid-schemas-rejected held at 0 (differential agree-valid unchanged).		2026-06-22 19:40:57 +02:00
