RE: The use cases table, modified, for comment

I interpreted this the same way as Ivan did. Michael C did indeed put this table together, largely based on that large call with PF and DPUB (and guests). Clarifying what is meant by role would go a long way.

That is of course correct. But I interpreted that option ("details with src and role") as providing the possibility to add a role that would make it clear that the src is some sort of an alternative description, ie, that it is not (necessarily) just a generic role.

Maybe it is worth making it clearer in the text what we really mean by this combination.
