28 /**
29  * Represents vCard's property, or logical "one line" of each vCard entry.
30  *
31  * e.g.
32  * Given a vCard below, objects for <code>N:name</code>, <code>TEL:1111111111</code> are
33  * "property".
34  *
35  * <code>
36  * BEGIN:VCARD
37  * N:name
38  * TEL:1111111111
39  * END:VCARD
40  * </code>
41  *
42  * vCard's property has three elements: name, parameter (or param), and value. Name is the name
43  * of each property. Parameter or param is additional information for the property. Value is one
44  * or multiple values representing the parameter.
45  *
46  * e.g.
47  * <code>N;CHARSET=UTF-8:Joe;Due;M.;Mr.;Ph.D.</code>, has "N" for name, "CHALSET=UTF-8" for param,
48  * and "Joe;Due;M.;Mr.;Ph.D." for value.
49  *
50  * Usually params are represented as "key=value" pair, but not always
51  * (The property <code>TEL;WORK;VOICE:(111) 555-1212</code> has two params without key "TYPE",
52  * which are same as "TYPE=WORK" and "TYPE=VOICE". In vCard 3.0, we can even express them as
53  * "TYPE=WORK,VOICE").
54  *
55  * Sometimes (not always) value can be separated by semi-colon. In the example above "Joe;Due;;;"
56  * should be interpreted as five strings: "Joe" (for family name), "Due" (for given name), "M."
57  * (for middle name), "Mr." (for prefix), and "Ph.D." (for suffix). Whether the value is
58  * separable or not is specified by vCard specs.
