unknown spec type importing from .reqif

I've been given an .reqif file that was generated at another site, and been asked to extract content.
I was hoping DoorScope import_documents->file option would work - but I receive an error: "Unknown specification type "_8dd..5a7c' on line 301197
I asked the DOORS admin to take a second snapshot of the design, however this new file exhibits the same problem (different identifier/line).
- am I misunderstanding the reqif file import use case?
- do I need to request that the remote doors admin use some options that may affect the reqif file exported by DOORS?
Any info very welcome!

DoorScope implements ReqIF version 1.1 and checks compatibility of the files based on the assertions required by the standard. If you get this error, either the file or the DoorScope implementation have issues. You can check the latter here: https://github.com/rochus-keller/DoorScope/blob/github/ReqIfParser.cpp#L440. Obviously a type definition is missing in the provided file. Do you have any information about the expected ReqIF version, or whether it is ReqIF at all? Maybe your admin could create a minimal document (or use one of the DOORS demo documents) and export it the same way your file was exported, so you could send me this as an example.

Yes I should have checked that, it is in fact only version 1.0.
<REQ-IF-VERSION>1.0</REQ-IF-VERSION>
I will request that the DOORS team generate a minimal document or if they are able to generate version 1.1 - that may take a few days though...
thanks for the information!
