+3. MIME Header Fields
+
+ MIME defines a number of new RFC 822 header fields that are used to
+ describe the content of a MIME entity. These header fields occur in
+ at least two contexts:
+
+ (1) As part of a regular RFC 822 message header.
+
+ (2) In a MIME body part header within a multipart
+ construct.
+
+ The formal definition of these header fields is as follows:
+
+ MIME-message-headers := entity-headers
+ fields
+ version CRLF
+ ; The ordering of the header
+ ; fields implied by this BNF
+ ; definition should be ignored.
+
+ MIME-part-headers := entity-headers
+ [ fields ]
+ ; Any field not beginning with
+ ; "content-" can have no defined
+ ; meaning and may be ignored.
+ ; The ordering of the header
+ ; fields implied by this BNF
+ ; definition should be ignored.
+
+ The syntax of the various specific MIME header fields will be
+ described in the following sections.
+
+Freed & Borenstein Standards Track [Page 11]
+RFC 2045 Internet Message Bodies November 1996
+
+5.1. Syntax of the Content-Type Header Field
+
+ In the Augmented BNF notation of RFC 822, a Content-Type header field
+ value is defined as follows:
+
+ content := "Content-Type" ":" type "/" subtype
+ *(";" parameter)
+ ; Matching of media type and subtype
+ ; is ALWAYS case-insensitive.
+
+ type := discrete-type / composite-type
+
+ discrete-type := "text" / "image" / "audio" / "video" /
+ "application" / extension-token
+
+ composite-type := "message" / "multipart" / extension-token
+
+ extension-token := ietf-token / x-token
+
+ ietf-token := <An extension token defined by a
+ standards-track RFC and registered
+ with IANA.>
+
+ x-token := <The two characters "X-" or "x-" followed, with
+ no intervening white space, by any token>
+
+ subtype := extension-token / iana-token
+
+ iana-token := <A publicly-defined extension token. Tokens
+ of this form must be registered with IANA
+ as specified in RFC 2048.>
+
+ parameter := attribute "=" value
+
+ attribute := token
+ ; Matching of attributes
+ ; is ALWAYS case-insensitive.
+
+ value := token / quoted-string
+
+ token := 1*<any (US-ASCII) CHAR except SPACE, CTLs,
+ or tspecials>
+
+ tspecials := "(" / ")" / "<" / ">" / "@" /
+ "," / ";" / ":" / "\" / <">
+ "/" / "[" / "]" / "?" / "="
+ ; Must be in quoted-string,
+ ; to use within parameter values
+
+ description := "Content-Description" ":" *text
+
+ encoding := "Content-Transfer-Encoding" ":" mechanism
+
+ entity-headers := [ content CRLF ]
+ [ encoding CRLF ]
+ [ id CRLF ]
+ [ description CRLF ]
+ *( MIME-extension-field CRLF )
+
+ hex-octet := "=" 2(DIGIT / "A" / "B" / "C" / "D" / "E" / "F")
+ ; Octet must be used for characters > 127, =,
+ ; SPACEs or TABs at the ends of lines, and is
+ ; recommended for any character not listed in
+ ; RFC 2049 as "mail-safe".
+
+RFC 2045 Internet Message Bodies November 1996
+
+ must be used. An equal sign as the last character on a
+ encoded line indicates such a non-significant ("soft")
+ line break in the encoded text.
+
+ Thus if the "raw" form of the line is a single unencoded line that
+ says:
+
+ Now's the time for all folk to come to the aid of their country.
+
+ This can be represented, in the Quoted-Printable encoding, as:
+
+ Now's the time =
+ for all folk to come=
+ to the aid of their country.
+
+ Since the hyphen character ("-") may be represented as itself in the
+ Quoted-Printable encoding, care must be taken, when encapsulating a
+ quoted-printable encoded body inside one or more multipart entities,
+ to ensure that the boundary delimiter does not appear anywhere in the
+ encoded body. (A good strategy is to choose a boundary that includes
+ a character sequence such as "=_" which can never appear in a
+ quoted-printable body. See the definition of multipart messages in
+ RFC 2046.)
