Add types for issuer authorities

[davux]

Add types and classes related to issue #2854:

• IssuerScope
• issuerFor
• hasIssuingAuthority
• delegationDepth

I would suggest that these new terms, if generally accepted, should be first placed in the pending area to enable assessment of use before moving into the core of the vocabulary.

It would also be helpful if they were accompanied by some examples so that potential implementers can gain insight as to how they would be used in a real world situation.

Also to add context to your proposal, who would consume such information?

Thanks for the suggestions @RichardWallis.

I did include a few examples on issue #2854, is that what you had in mind? Or do you mean in the description of each term in the schema?

As for the inclusion in pending, is that a different process or is this PR OK?

[RichardWallis]

To be placed in pending, a .ttl file containing the term definitions (the convention being it is named after the original issue) should be placed in the data/ext/pending directory. Plus all such terms should be marked :isPartOf <https://pending.schema.org> ; - see others in directory (eg. issue-1758.ttl)

As for examples, that would appear on the term definition pages. What you included in your issue comments could indeed be part of a real, or imagined, example showing how you would mark up related entities using these terms. Such as detailed in issue-1758-examples.txt

Thanks for the suggestions @RichardWallis. I've moved the definition to pending.

As for the examples, I'm seeing a markup that looks like #eg-nnnn that seem to be unique and incrementing numbers. What's the exact rule? How do I make sure there is no clash with other pending contributions?
