from the roa draft:

2.1.3.2. eContent

   The content of a ROA identifies a single AS that has been authorized
   by the address space holder to originate routes and a list of one or
   more IP address prefixes that will be advertised.  If the address
   space holder needs to authorize multiple ASes to advertise the same
   set of address prefixes, the holder issues multiple ROAs, one per AS
   number.

and

4. Security Considerations


....   The purpose of a ROA is to convey authorization for an AS to
   originate a route to the prefix(es) in the ROA.

these are basic, clear, simple, concise, terse, and rigorous  
definition of the semantics of a roa.
