-/**
- * $Id$
- * 
- * Created: [Apr 6, 2004]
- *
- * Defines a CATEGORIES iCalendar component property.
- * <pre>
- *     4.8.1.2 Categories
- *     
- *        Property Name: CATEGORIES
- *     
- *        Purpose: This property defines the categories for a calendar
- *        component.
- *     
- *        Value Type: TEXT
- *     
- *        Property Parameters: Non-standard and language property parameters
- *        can be specified on this property.
- *     
- *        Conformance: The property can be specified within "VEVENT", "VTODO"
- *        or "VJOURNAL" calendar components.
- *     
- *        Description: This property is used to specify categories or subtypes
- *        of the calendar component. The categories are useful in searching for
- *        a calendar component of a particular type and category. Within the
- *        "VEVENT", "VTODO" or "VJOURNAL" calendar components, more than one
- *        category can be specified as a list of categories separated by the
- *        COMMA character (US-ASCII decimal 44).
- *     
- *        Format Definition: The property is defined by the following notation:
- *     
- *          categories = "CATEGORIES" catparam ":" text *("," text)
- *                       CRLF
- *     
- *          catparam   = *(
- *     
- *                     ; the following is optional,
- *                     ; but MUST NOT occur more than once
- *     
- *                     (";" languageparam ) /
- *     
- *                     ; the following is optional,
- *                     ; and MAY occur more than once
- *     
- *                     (";" xparam)
- *     
- *                     )
- * </pre>
