2. Syntax of encoded-words
An "encoded-word" is defined by the following ABNF grammar. The
notation of RFC 822 is used, with the exception that white space
characters MAY NOT appear between components of an encoded-word.
encoded-word = "=?" charset "?" encoding "?" encoded-text "?="
charset = token ; see section 3
encoding = token ; see section 4
token = 1*<Any CHAR except SPACE, CTLs, and especials>
especials = "(" / ")" / "<" / ">" / "@" / "," / ";" / ":" / "
<"> / "/" / "[" / "]" / "?" / "." / "="
The second last line is syntactically malformed and should be,
I think:
: especials = "(" / ")" / "<" / ">" / "@" / "," / ";" / ":" / "\" /
General question: How are normally simple corrections to already
published RFCs like this one handled? Is a "second, corrected
edition" issued or a new RFC with a new number?
