I'm maintaining a project that uses this module. I can't say I understand the module very well, since I haven't used it much, so I appreciate your patience and understanding if I'm confused about something.
It's my understanding that the "id" field in incoming data is a set of fields whose values constitute a unique ID. In our incoming data, the fields that we treat as "ids" are actual UUIDs (e.g., 9592b6c1-6c90-4b4c-b044-43b0df8b87c6). When we try to process this data in a migration, we get the following error message:
The id (Example) must only include word characters a-z, A-Z, 0-9, including _ (underscore)
I think hyphens (the - character) should be allowed, so that fields containing UUIDs can be used.
Closed: won't fix

I just realized this deals with ID titles, not values. Apologies for the confusion.
Is there any reason the ID titles must be limited to these characters? It seems spaces in titles were allowed in a previous version.
