      [Proposed]

    • Proposal:
      Hide

      Define special separator rules for header values (OWS is only used in headers, and "bad whitespace" is only used surrounding the EQ sign):

      OWS = *( SP / HTAB ) ; "optional" whitespace
      BWS-h = *( SP / HTAB ) ; "bad" whitespace in header values
      EQ-h = BWS-h EQ BWS-h

      Use these in header-related rules, e.g.:

      callbackPreference = "odata.callback" OWS ";" OWS "url" EQ-h DQUOTE URI DQUOTE

      Description

      Section 8. Header values re-uses punctuation rules OWS and BWS that were intended for raw URLs and thus allow percent-encoded spaces and tabs. Within headers these are not valid.
