TalentSignal: How to express that something isn't required

Hello all, I've been asked a question that relates to talent signaling, 
specifically schema.org/JobPosting <https://schema.org/JobPosting>, 
which is "how would you indicate that qualification/credential is not 
required?"

The use case is for focusing a service on opportunities for people with 
limited educational qualifications (e.g. no degree required) but I think 
it also generalizes to things like "no driving licence required" and I 
guess "no previous experience required".

We don't think there is currently any way in schema.org/JobPosting to 
show this information, and it's kind of problematic to either have 
properties for the endless list of what's not required or to assume that 
just because a requirement isn't listed in the structured data then it 
doesn't exist.

I would welcome any insights on how this is handled in other HR data 
standards and systems.

All the best, Phil
