    1287             <p id="rfc.section.3.2.p.4">Extraction of field-name/field-value pairs from a message is generic and thus independent of the actual field name. Consequently,
    1288                the ABNF specified for each header field only defines the syntax of the field-value (not the whole header-field, as it was
    1289                the case in previous revisions of this specification).
     1287            <p id="rfc.section.3.2.p.4">Since messages are parsed using a generic algorithm, independent of the individual header field names, the contents within
     1288               a given field-value are not parsed until a later stage of message interpretation (usually after the message's entire header
     1289               section has been processed). Consequently, this specification does not use specific ABNF rules to define each "Field-Name:
     1290               Field Value" pair, as was done in previous editions. Instead, this specification defines each of its header fields using an
     1291               ABNF rule that is named according to the registered field-name and that defines only the syntax within the field-value (i.e.,
     1292               after it has been extracted from the header section by a generic field parser).
