My preferred scenario would be to have an identifier on every node

some types, such as entry subtypes and a few more. If it cannot be

What is the meaning of overhead here? Processing time? Memory/disk
space? According to which criteria the overhead is quantified as
"quite a lot"?
You can see I'm not really convinced here :)
perfectly reasonable ... But I actually did calculations a few years ago
on the overhead imposed by ISO 13606, which would force UIDs everywhere.
It's quite significant based on a reasonable sample of mixed EHR data,
mainly because Guids are much longer than a lot of values. I will try to
locate this. But it's not hard to replicate.
When one is purchasing terabyte RAID 10 secure storage, adding another
20% or even 10% starts to matter.
