I am behind a few releases, so don’t completely grok “lead node”. Is what you are describing look like this:
authors:
- Alice
- Frank
annotators:
- Bob
recipients:
- Carol
- Dan
- Eve
I think what you are describing is that the following paths are created:
/persons/alice
/persons/bob
/persons/carol
/persons/dan
/persons/eve
/persons/frank
A page won’t be created for /persons/authors/alice, but you can still use implied hierarchy to range over a list of content where Alice was an author. Is that correct?
Also, sorry if this is stale; a cursory issue search didn’t find anything about this.
