Presentation Definition: be lenient about single-entry arrays v.s. singular values #4126
Description
credentialSubject can be an array or a single object. The Presentation Definition specify to handle both, unless it's 100% certain it's one of them.
However, this is quite error prone. Maybe we should treat single-entry arrays and singular values the same when matching Presentation Definitions, regardless whether we're indexing an array (entry 0) or not?
Meaning, these Presentation Definition constraint paths are equivalent when the credentialSubject is an array or an object:
credentialSubject[0].some.other.propertycredentialSubject.some.other.property
If credentialSubject is an array with multiple entries, or the credentialSubject[x] is indexed with x != 0, this semantic doesn't apply.
