2.6 Line Delimiting and Folding

   This profile supports the same line delimiting and folding methods
   defined in [MIME-DIR]. Specifically, when parsing a content line,
   folded lines must first be unfolded according to the unfolding
   procedure described in [MIME-DIR]. After generating a content line,
   lines longer than 75 characters SHOULD be folded according to the
   folding procedure described in [MIME DIR].

   Folding is done after any content encoding of a type value. Unfolding
   is done before any decoding of a type value in a content line.

3.  vCard Profile Features

   The vCard MIME Directory Profile Type contains directory information,
   typically pertaining to a single directory entry. The information is
   described using an attribute schema that is tailored for capturing
   personal contact information. The vCard can include attributes that
   describe identification, delivery addressing, telecommunications
   addressing, geographical, organizational, general explanatory and
   security and access information about the particular object
   associated with the vCard.

3.1 Identification Types

   These types are used in the vCard profile to capture information
   associated with the identification and naming of the person or
   resource associated with the vCard.

RFC 2426              vCard MIME Directory Profile        September 1998


   Type encoding: 8bit

   Type value: A single text value.

   Type special notes: This type is based on the semantics of the X.520
   Common Name attribute. The property MUST be present in the vCard
   object.

   Type example:

        FN:Mr. John Q. Public\, Esq.

3.1.2 N Type Definition

   To: [e-mail]

   Subject: Registration of text/directory MIME type N

   Type name: N

   Type purpose: To specify the components of the name of the object the
   vCard represents.

   Type encoding: 8bit

   Type value: A single structured text value. Each component can have
   multiple values.

   Type special note: The structured type value corresponds, in
   sequence, to the Family Name, Given Name, Additional Names, Honorific
   Prefixes, and Honorific Suffixes. The text components are separated
   by the SEMI-COLON character (ASCII decimal 59). Individual text
   components can include multiple text values (e.g., multiple
   Additional Names) separated by the COMMA character (ASCII decimal
   44). This type is based on the semantics of the X.520 individual name
   attributes. The property MUST be present in the vCard object.

   Type example:

        N:Public;John;Quinlan;Mr.;Esq.

        N:Stevenson;John;Philip,Paul;Dr.;Jr.,M.D.,A.C.P.

RFC 2426              vCard MIME Directory Profile        September 1998


   Type name: NICKNAME

   Type purpose: To specify the text corresponding to the nickname of
   the object the vCard represents.

   Type encoding: 8bit

   Type value: One or more text values separated by a COMMA character
   (ASCII decimal 44).

   Type special note: The nickname is the descriptive name given instead
   of or in addition to the one belonging to a person, place, or thing.
   It can also be used to specify a familiar form of a proper name
   specified by the FN or N types.

   Type example:

        NICKNAME:Robbie

        NICKNAME:Jim,Jimmie

3.1.4 PHOTO Type Definition

   To: [e-mail]

   Subject: Registration of text/directory MIME type PHOTO

   Type name: PHOTO

   Type purpose: To specify an image or photograph information that
   annotates some aspect of the object the vCard represents.

   Type encoding: The encoding MUST be reset to "b" using the ENCODING
   parameter in order to specify inline, encoded binary data. If the
   value is referenced by a URI value, then the default encoding of 8bit
   is used and no explicit ENCODING parameter is needed.

   Type value: A single value. The default is binary value. It can also
   be reset to uri value. The uri value can be used to specify a value
   outside of this MIME entity.

   Type special notes: The type can include the type parameter "TYPE" to
   specify the graphic image format type. The TYPE parameter values MUST
   be one of the IANA registered image formats or a non-standard image
   format.

RFC 2426              vCard MIME Directory Profile        September 1998


   Type purpose: To specify the components of the delivery address for
   the vCard object.

   Type encoding: 8bit

   Type value: A single structured text value, separated by the
   SEMI-COLON character (ASCII decimal 59).

   Type special notes: The structured type value consists of a sequence
   of address components. The component values MUST be specified in
   their corresponding position. The structured type value corresponds,
   in sequence, to the post office box; the extended address; the street
   address; the locality (e.g., city); the region (e.g., state or
   province); the postal code; the country name. When a component value
   is missing, the associated component separator MUST still be
   specified.

   The text components are separated by the SEMI-COLON character (ASCII
   decimal 59). Where it makes semantic sense, individual text
   components can include multiple text values (e.g., a "street"
   component with multiple lines) separated by the COMMA character
   (ASCII decimal 44).

   The type can include the type parameter "TYPE" to specify the
   delivery address type. The TYPE parameter values can include "dom" to
   indicate a domestic delivery address; "intl" to indicate an
   international delivery address; "postal" to indicate a postal
   delivery address; "parcel" to indicate a parcel delivery address;
   "home" to indicate a delivery address for a residence; "work" to
   indicate delivery address for a place of work; and "pref" to indicate
   the preferred delivery address when more than one address is
   specified. These type parameter values can be specified as a
   parameter list (i.e., "TYPE=dom;TYPE=postal") or as a value list
   (i.e., "TYPE=dom,postal"). This type is based on semantics of the
   X.520 geographical and postal addressing attributes. The default is
   "TYPE=intl,postal,parcel,work". The default can be overridden to some
   other set of values by specifying one or more alternate values. For
   example, the default can be reset to "TYPE=dom,postal,work,home" to
   specify a domestic delivery address for postal delivery to a
   residence that is also used for work.

   Type example: In this example the post office box and the extended
   address are absent.

        ADR;TYPE=dom,home,postal,parcel:;;123 Main
          Street;Any Town;CA;91921-1234

3.2.2 LABEL Type Definition

   To: [e-mail]

   Subject: Registration of text/directory MIME type LABEL

   Type name: LABEL

   Type purpose: To specify the formatted text corresponding to delivery
   address of the object the vCard represents.

   Type encoding: 8bit

   Type value: A single text value.

   Type special notes: The type value is formatted text that can be used
   to present a delivery address label for the vCard object. The type
   can include the type parameter "TYPE" to specify delivery label type.
   The TYPE parameter values can include "dom" to indicate a domestic
   delivery label; "intl" to indicate an international delivery label;
   "postal" to indicate a postal delivery label; "parcel" to indicate a
   parcel delivery label; "home" to indicate a delivery label for a
   residence; "work" to indicate delivery label for a place of work; and
   "pref" to indicate the preferred delivery label when more than one
   label is specified. These type parameter values can be specified as a
   parameter list (i.e., "TYPE=dom;TYPE=postal") or as a value list
   (i.e., "TYPE=dom,postal"). This type is based on semantics of the
   X.520 geographical and postal addressing attributes. The default is
   "TYPE=intl,postal,parcel,work". The default can be overridden to some
   other set of values by specifying one or more alternate values. For
   example, the default can be reset to "TYPE=intl,post,parcel,home" to
   specify an international delivery label for both postal and parcel
   delivery to a residential location.

   Type example: A multi-line address label.

        LABEL;TYPE=dom,home,postal,parcel:Mr.John Q. Public\, Esq.\n
         Mail Drop: TNE QB\n123 Main Street\nAny Town\, CA  91921-1234

   Type purpose: To specify the telephone number for telephony
   communication with the object the vCard represents.

   Type encoding: 8bit

   Type value: A single phone-number value.

   Type special notes: The value of this type is specified in a
   canonical form in order to specify an unambiguous representation of
   the globally unique telephone endpoint. This type is based on the
   X.500 Telephone Number attribute.

   The type can include the type parameter "TYPE" to specify intended
   use for the telephone number. The TYPE parameter values can include:
   "home" to indicate a telephone number associated with a residence,
   "msg" to indicate the telephone number has voice messaging support,
   "work" to indicate a telephone number associated with a place of
   work, "pref" to indicate a preferred-use telephone number, "voice" to
