    103 The wording for the credential is a little complex, but it says "Any principal that has a ''P''.'''CTFcontestant''' attribute where ''P'' that has the '''ACM.gamerep''' attribute has the '''GENI.CTFaccess''' attribute, signed GENI".  More simply, the ACM principal can designate representatives by giving them the '''ACM.CTFrep''' attribute; when those representatives give another principal their '''.CTFcontestant''' attribute, the principal with that attribute is given the '''GENI.CFTaccess''' attribute.  ACM representatives can grant access to the slice.

    105105An advantage of this is that it creates a new administrative group - ACM's game representatives - that can be useful in other contexts. For example, this same group of representatives can designate contestants for other competitions or other attributes relevant to the capture the flag contest without further changes by the ACM.  Delegating through individual ACM attributes would require continuing work by the ACM.
