Type: Technical
Reported by: Dylan Allbee <[e-mail]>

Section: 4.3,

Original Text
-------------
Enumerations have the same representation as signed integers.
Enumerations are handy for describing subsets of the integers.
Enumerated data is declared as follows:

    enum { name-identifier = constant, ... } identifier;

For example, the three colors red, yellow, and blue could be
described by an enumerated type:

    enum { RED = 2, YELLOW = 3, BLUE = 5 } colors;

Corrected Text
--------------
...

    enum identifier { name-identifier = constant, ... } ;
         ^^^^^^^^^^

...

    enum colors { RED = 2, YELLOW = 3, BLUE = 5 } ;
         ^^^^^^ 

Notes
-----
The grammar for this definition, as specified in 6.3, is:

    type-def:
           "typedef" declaration ";"
         | "enum" identifier enum-body ";"
         | "struct" identifier struct-body ";"
         | "union" identifier union-body ";"

It is unclear whether the original intent was for identifies to precede or succeed the definition bodies. The example in section 7 shows: enum filekind { ... }

And several RFCs which depend on 4506 have also followed that pattern, such as this example from RFC 5531, section 8.2: enum auth_flavor { ... }
