43 * $Id$
44 *
45 * Created: [Apr 6, 2004]
46 *
47 * Defines a CATEGORIES iCalendar component property.
48 * <pre>
49 * 4.8.1.2 Categories
50 *
51 * Property Name: CATEGORIES
52 *
53 * Purpose: This property defines the categories for a calendar
54 * component.
55 *
56 * Value Type: TEXT
57 *
58 * Property Parameters: Non-standard and language property parameters
59 * can be specified on this property.
60 *
61 * Conformance: The property can be specified within "VEVENT", "VTODO"
62 * or "VJOURNAL" calendar components.
63 *
64 * Description: This property is used to specify categories or subtypes
65 * of the calendar component. The categories are useful in searching for
66 * a calendar component of a particular type and category. Within the
67 * "VEVENT", "VTODO" or "VJOURNAL" calendar components, more than one
68 * category can be specified as a list of categories separated by the
69 * COMMA character (US-ASCII decimal 44).
70 *
71 * Format Definition: The property is defined by the following notation:
72 *
73 * categories = "CATEGORIES" catparam ":" text *("," text)
74 * CRLF
75 *
76 * catparam = *(
77 *
78 * ; the following is optional,
79 * ; but MUST NOT occur more than once
80 *
81 * (";" languageparam ) /
82 *
83 * ; the following is optional,
84 * ; and MAY occur more than once
85 *
86 * (";" xparam)
87 *
88 * )
