This is already done in the R5 version

This is already done in R5 - just have to copy the same code across

this seems like a very unlikely change to make for the *validator*. There'd really be no way to decide if the content was valid or not

So how do things stand now?

General scheme for doing this: * if an extension is found in the source that has this kind of path * if the path corresponds to this + a property...

Asked the original reporter for a test case

And nor do I understand why this code does these changes for the IdType, where | is an illegal character

what language did you try?

is this a good feature, is it? How would it work from a user point of view?

discussion amongst the committers: * we won't enable this by default (may have unexpected side effects in existing deployments) * whatever we do, has to work for validator.fhir.org as well...
