Yep i fixed this one yesterday - sorry, I should have written these down. Should be `pattern_constraint`.

yep - I fixed those, that is incorrect.

yes, otherwise the object does not need to exist.

That appears to be a missing ‘include’ line in the Resource spec - I’ll fix that. ([Here it is in the UML site)](https://specifications.openehr.org/releases/UML/latest/index.html#Architecture___18_1_83e026d_1429721427946_83239_4696).

That’s a BMM error I missed; will correct.

> ARCHETYPE\_HRID.namespace is incorrectly mandatory in the base 1.1.0 BMM

Ok - corrections to do there as well.

Teamwork rules 😉
