Hi again,

I should probably also mention that we need some document that provides
recommendations about how archetypes should be created when there are more
than one way to do it like the example below. Otherwise there is a risk that
there are too many archetypes with different representations that
essentially mean the same thing.

The rules that Thomas talked about in this thread
http://www.openehr.org/advice/implementers-priv/msg00311.html , i.e.

- if there is a plug-in C_DOMAIN_TYPE type available, always use it to
represent constraints for the corresponding RM type
- if there is a syntax equivalent for this type, then use it
- otherwise use generic ADL


Should also be documented somewhere.

Regards,

Mattias
