Here are my name preferences for the WG...

*Wouldn't Object:*

        * TxAuth      Transmission of Authority
        * AZARP    AuthoriZed Access to Resources Protocol
        * GNAP    Grant Negotiation and Authorization Protocol
        * NIRAD    Negotiation of Intent Registration and Authority
Delegation
        * PAuthZ    Protocol for Authorization
        * TIAAP    Tokenized Identity and Access Protocol

I feel these all have the right mix of identifiable/unique short names,
along with expansions that both describe and define the overall subject
area we're addressing - without imposing any hard-edges if you know what I
mean.

*Object:*

All the other candidates, for reasons including:
+ not describing or defining anything (eg. "Alternative", "BYO", "DIY",
"Reimagined")
+ being too hard-edged (eg. "Testable", "This is not...", "Truly",
"Refactored")
+ prone to pre-conceived notions (eg. anything with "Extension")
+ being an acronym looking for a name (eg. "CPAAP", "AZARAP", "GranPro",
"TIDYAuth"

Thanks for your consideration,
Hankins Parichabutr
