In openEHR as it stands now, the answer would be no, because the
snomed-ct:263495000 code is just one binding to at0017. What is reliable
in the data is the at0017 internal code.
In future, it is not out of the question that different types of OPTs
would be generated that would treat bound terminology codes as if they
were the structural ones, but this is probably a long way off. Some
further ideas about this in the ADL2 spec
<https://www.openehr.org/releases/AM/latest/docs/ADL2/ADL2.html#_terminology_integration>,
and also the OPT2 spec
<https://www.openehr.org/releases/AM/latest/OPT2.html>.
It also might not be hard to preprocess AQL queries written like this
into the standard form, but that would require that the code
snomed-ct:263495000 be bound uniquely to at0017, and no other node code
e.g. at0015. So doing this would require stricter binding rules than we
currently have, and which I think are not semantically justifiable.

Hello,
In AQL it is possible to constrain the value of a node to one of the
codes that are allowed for that value (as specified in the respective
archetype).
To find patients with gender (snomed-ct:248153007) male
(snomed-ct:248153007) I could write something like this:
SELECT e FROMEHR e CONTAINSDEMOGRAPHICS d
WHERE d.items[at0017].value = 'snomed-ct:248153007'
Is it possible to identify the node of an archetype instead of its
path parts (e.g. d.gender or d.items[at0017]) also with a terminology
code, so the query would rather look like something like that:
SELECT e FROMEHR e CONTAINSDEMOGRAPHICS d
WHERE d.items['snomed-ct:263495000'].value = 'snomed-ct:248153007'
I am not very experienced with AQL so the queries are probably already
syntactically wrong.
