Implementation Details

The ANVL Internet-Draft of 14 February, 2005 is inspecific as to the definition of 'blank line' and 'newline'. This parser implementation assumes CRNL.

Says "An element consists of a label, a colon, and an optional value". Should that be: "An element consists of a label and an optional value, or a comment."

Specification is unclear regards CR or NL in label or comment (This implementation disallows CR or NL in labels but lets them pass in comments).

A grammar would help. Here is RFC822:

     field       =  field-name ":" [ field-body ] CRLF
     
     field-name  =  1*<any CHAR, excluding CTLs, SPACE, and ":">
     
     field-body  =  field-body-contents
                    [CRLF LWSP-char field-body]
     
     field-body-contents =
                   <the ASCII characters making up the field-body, as
                    defined in the following sections, and consisting
                    of combinations of atom, quoted-string, and
                    specials tokens, or else consisting of texts>
