Please change the delimiter to ||, or better yet to ?? So that is it more natural to read.

Had a really quick look, but do the default values actually work?

Fixed, using ?? both also supports ||

Tested all three states, also after the ?? change

The correlationIds map VCI option files onto VCI metadata and VP option files onto presentation_definitions files. So they need to be unique for a tuple of these files. For now a correlationId related to VCI does not affect VP or vice versa, so there can be overlap between these. However it is wise to just have a correlationId unique per ecosystem, which then is present in a single file for VCI options, VCI metadata, VP options and presentation_definition

Current changes to correlationId do not ensure that. We can/should just use another identifier for the them, like for instance the ecosystem name
