Look again. This time look at page 474 of the RM, in the summary of
Language Defined Attributes.

You will find the following:

S'Pos  For every discrete subtype S:
       
       S'Pos denotes a function with the following specification:
           function S'Pos(Arg : S'Base) return universal_integer

       This function returns the position number of the value Arg,
       as a value of type universal_integer. 

All enumeration types are discrete types.
