Hi all, we’d like to be able to choose “drops” as a unit within Archetype Designer (and other tooling). It is a valid UCUM unit, so I’ve raised a [PR with it added to PropertyUnitData.xml](https://github.com/openEHR/specifications-TERM/pull/16). Is that correct approach, and is there anything else I need to do?

@siljelb . I guess this is a reasonable request?

Certainly, although I’m a bit unsure about the maths. I’ve submitted a change request to the PR.

Hi @siljelb , is there anything else we need to do get the change merged, or will it get picked up as part of a release cycle?
