Parameter Name
VALUE
Purpose
To explicitly specify the value type format for a property value.
Format Definition
This property parameter is defined by the following notation:
valuetypeparam = "VALUE" "=" valuetype
valuetype = ("BINARY" / "BOOLEAN" / "CAL-ADDRESS" / "DATE" / "DATE-TIME" / "DURATION" / "FLOAT" / "INTEGER" / "PERIOD" / "RECUR" / "TEXT" / "TIME" / "URI" / "UTC-OFFSET" / x-name ; Some experimental iCalendar value type. / iana-token) ; Some other IANA-registered iCalendar value type.
Description
This parameter specifies the value type and format of the property value. The property values MUST be of a single value type. For example, a "RDATE" property cannot have a combination of DATE-TIME and TIME value types.
If the property's value is the default value type, then this parameter need not be specified. However, if the property's default value type is overridden by some other allowable value type, then this parameter MUST be specified.
Applications MUST preserve the value data for x-name and iana- token values that they don't recognize without attempting to interpret or parse the value data.
