{ TODO:
Agent property does not work and the current parsing stops whenever it
sees END:VCard meaning that the VCard will be truncated if AGENT is
used to embed a VCard.
I omitted a property for spelling out a sound. Appearently VCard 2.1
permitted a charactor representation of sound in addition to an embedded
sound, and a URL.
I am not sure how well the KEY property works. That is used for
embedding some encryption keys into a VCard such as PGP public-key or
something from Versign.
VCard does not have any Quoted Printable decoding or Base64 encoding
and decoding. Some routines may have to be changed to accomodate
this although I don't have the where-with-all.
VCards can not be saved. }

"date", "time", and "date-time": Each of these value types is based
on a subset of the definitions in ISO 8601 standard. Profiles MAY
place further restrictions on "date" and "time" values. Multiple
"date" and "time" values can be specified using the comma-separated
notation, unless restricted by a profile.
Examples for "date":

time-value = <A single time value as defined in [MIME-DIR]>
date-time-value = <A single date-time value as defined in [MIME-DIR]
[MIME-DIR] Howes, T., Smith, M., and F. Dawson, "A MIME Content-
Type for Directory Information", RFC 2425, September
1998.
Per RFC 6350 Section 4.3:
"date", "time", "date-time", "date-and-or-time", and "timestamp":
Each of these value types is based on the definitions in
[ISO.8601.2004]. Multiple such values can be specified using the
comma-separated notation.
Only the basic format is supported.
4.3.1. DATE
A calendar date as specified in [ISO.8601.2004], Section 4.1.2.
Reduced accuracy, as specified in [ISO.8601.2004], Sections 4.1.2.3
a) and b), but not c), is permitted.
Expanded representation, as specified in [ISO.8601.2004], Section
4.1.4, is forbidden.
Truncated representation, as specified in [ISO.8601.2000], Sections
5.2.1.3 d), e), and f), is permitted.
Examples for "date":
19850412
1985-04
1985
--0412
---12
Note the use of YYYY-MM in the second example above. YYYYMM is
disallowed to prevent confusion with YYMMDD. Note also that
YYYY-MM-DD is disallowed since we are using the basic format instead
of the extended format.
4.3.2. TIME
A time of day as specified in [ISO.8601.2004], Section 4.2.
Reduced accuracy, as specified in [ISO.8601.2004], Section 4.2.2.3,
is permitted.
Representation with decimal fraction, as specified in
[ISO.8601.2004], Section 4.2.2.4, is forbidden.
The midnight hour is always represented by 00, never 24 (see
[ISO.8601.2004], Section 4.2.3).
Truncated representation, as specified in [ISO.8601.2000], Sections
5.3.1.4 a), b), and c), is permitted.
Examples for "time":
102200
1022
10
-2200
--00
102200Z
102200-0800
4.3.3. DATE-TIME
A date and time of day combination as specified in [ISO.8601.2004],
Section 4.3.
Truncation of the date part, as specified in [ISO.8601.2000], Section
5.4.2 c), is permitted.
Examples for "date-time":
19961022T140000
--1022T1400
---22T14
4.3.4. DATE-AND-OR-TIME
Either a DATE-TIME, a DATE, or a TIME value. To allow unambiguous
interpretation, a stand-alone TIME value is always preceded by a "T".
Examples for "date-and-or-time":
19961022T140000
