Hi Birger,
Note that no openEHR RM types (COMPOSITION etc) are part of the AQL spec
- they are just used in examples. AQL doesn't actually know anytthing
about particular types. Seref's intention is that it stays this way, and
his proposed function, or some other equivalent resolver mechanism would
be a generic addition to AQL that would, for openEHR structures be used
for FOLDERs containing refs to COMPOSITIONs (actually
VERSIONED_COMPOSITIONs), and also any other similar situation (e.g. in
the demographic model).

Hi Seref,
while I understand your argument regarding overloading of definitions
(and I agree with your reasoning), I see a clear need to not treat
folders as second class citizens in openEHR. Not including Folders in
the official AQL spec and leaving this to vendor-dependent functions
will not be helpful to allow portability. Especially, as the use of
folders (especially when it can contain data in an ITEM_STRUCTURE) is
becoming a common pattern to represent episodes of care.
Cheers,
