/* RFC 3501 7.4.2 BODYSTRUCTURE
BODY A form of BODYSTRUCTURE without extension data.
A parenthesized list that describes the [MIME-IMB] body
structure of a message. This is computed by the server by
parsing the [MIME-IMB] header fields, defaulting various fields
as necessary.
For example, a simple text message of 48 lines and 2279 octets
can have a body structure of: ("TEXT" "PLAIN" ("CHARSET"
"US-ASCII") NIL NIL "7BIT" 2279 48)
Multiple parts are indicated by parenthesis nesting. Instead
of a body type as the first element of the parenthesized list,
there is a sequence of one or more nested body structures. The
second element of the parenthesized list is the multipart
subtype (mixed, digest, parallel, alternative, etc.).
For example, a two part message consisting of a text and a
BASE64-encoded text attachment can have a body structure of:
(("TEXT" "PLAIN" ("CHARSET" "US-ASCII") NIL NIL "7BIT" 1152
23)("TEXT" "PLAIN" ("CHARSET" "US-ASCII" "NAME" "cc.diff")
"<*****@*****.**>" "Compiler diff"
"BASE64" 4554 73) "MIXED")
Extension data follows the multipart subtype. Extension data
is never returned with the BODY fetch, but can be returned with
a BODYSTRUCTURE fetch. Extension data, if present, MUST be in
the defined order. The extension data of a multipart body part
are in the following order:
body parameter parenthesized list
A parenthesized list of attribute/value pairs [e.g., ("foo"
"bar" "baz" "rag") where "bar" is the value of "foo", and
"rag" is the value of "baz"] as defined in [MIME-IMB].
body disposition
A parenthesized list, consisting of a disposition type
string, followed by a parenthesized list of disposition
attribute/value pairs as defined in [DISPOSITION].
body language
A string or parenthesized list giving the body language
value as defined in [LANGUAGE-TAGS].
body location
A string list giving the body content URI as defined in [LOCATION].
Any following extension data are not yet defined in this
version of the protocol. Such extension data can consist of
zero or more NILs, strings, numbers, or potentially nested
parenthesized lists of such data. Client implementations that
do a BODYSTRUCTURE fetch MUST be prepared to accept such
extension data. Server implementations MUST NOT send such
extension data until it has been defined by a revision of this
protocol.
The basic fields of a non-multipart body part are in the
following order:
body type
A string giving the content media type name as defined in [MIME-IMB].
body subtype
A string giving the content subtype name as defined in [MIME-IMB].
body parameter parenthesized list
A parenthesized list of attribute/value pairs [e.g., ("foo"
"bar" "baz" "rag") where "bar" is the value of "foo" and
"rag" is the value of "baz"] as defined in [MIME-IMB].
body id
A string giving the content id as defined in [MIME-IMB].
body description
A string giving the content description as defined in [MIME-IMB].
body encoding
A string giving the content transfer encoding as defined in [MIME-IMB].
body size
A number giving the size of the body in octets. Note that
this size is the size in its transfer encoding and not the
resulting size after any decoding.
A body type of type MESSAGE and subtype RFC822 contains,
immediately after the basic fields, the envelope structure,
body structure, and size in text lines of the encapsulated
message.
A body type of type TEXT contains, immediately after the basic
fields, the size of the body in text lines. Note that this
size is the size in its content transfer encoding and not the
resulting size after any decoding.
Extension data follows the basic fields and the type-specific
fields listed above. Extension data is never returned with the
BODY fetch, but can be returned with a BODYSTRUCTURE fetch.
Extension data, if present, MUST be in the defined order.
The extension data of a non-multipart body part are in the
following order:
body MD5
A string giving the body MD5 value as defined in [MD5].
body disposition
A parenthesized list with the same content and function as
the body disposition for a multipart body part.
body language
A string or parenthesized list giving the body language
value as defined in [LANGUAGE-TAGS].
body location
A string list giving the body content URI as defined in [LOCATION].
Any following extension data are not yet defined in this
version of the protocol, and would be as described above under
multipart extension data.
// We don't construct extention fields like rfc says:
Server implementations MUST NOT send such
extension data until it has been defined by a revision of this
protocol.
