@jsnyder sent me this message, unfortunately he can’t post here for some reason, so I’m adding this for him. He makes a good point, I don’t have knowledge of LOINC’s rules/efforts in this area but it makes sense to be consistent and use any prework.
Hi Dion,
Thank you for taking the time to pull this proposal together and post it to the forum. Unfortunately, I do not have permissions to respond to forum posts for the TRAG even though I would like to fully support this proposal.
One area that I would like the TRAG to take into consideration is to review the proposal within the scope of the LOINC/SNOMED Cooperation work. LOINC has suffered from the presence of these characters in their content for over a decade now with the non-printable space being specifically troublesome for implementors. I would like to see whatever solution SNOMED adopts be inclusive and/or exclusive enough in the rule set to accommodate the LOINC content so that the extension doesn’t need to modify the rule set just for their content.
Please let me know if you have any questions or what we can do to help you move this proposal forward.
Thanks
John
