RFC 4324                Calendar Access Protocol           December 2005


6.1.1.8.  DTEND and DURATION

   The "DTEND" property value is not included in the time occupied by
   the component.  That is, a "DTEND" property value of 20030614T12000
   includes all of the time up to, but not including, noon on that day.

   The "DURATION" property value end time is also not inclusive.  So an
   object with a "DTSTART" property value of 20030514T110000 and a
   "DURATION" property value of "1H" does not include noon on that day.

   When a "QUERY" property value contains a "DTEND" value, then the CS
   MUST also evaluate any existing "DURATION" property value and
   determine if it has an effective end time that matches the "QUERY"
   property supplied "DTEND" value or any range of values supplied by
   the "QUERY" property.

   When a "QUERY" property contains a "DURATION" value, then the CS MUST
   also evaluate any existing "DTEND" property values and determine if
   they have an effective duration that matches the value, or any range
   of values, supplied by the "QUERY" property.

6.1.1.9.  [NOT] LIKE

   The pattern matching characters are the '%' that matches zero or more
   characters, and '_' that matches exactly one character (where
   character does not always mean octet).

   "LIKE" clause pattern matches always cover the entire string.  To
   match a pattern anywhere within a string, the pattern must start and
   end with a percent sign.

   To match a '%' or '_' in the data and not have it interpreted as a
   wildcard character, they MUST be backslash-escaped.  Thus, to search
   for a '%' or '_' in the string:

      LIKE '%\%%'    Matches any string with a '%' in it.
      LIKE '%\_%'    Matches any string with a '_' in it.

   Strings compared using the "LIKE" clause MUST be performed using case
   insensitive comparisoison assumes 'a' = 'A').

   If the "LIKE" clause is preceded by 'NOT' then there is a match when
   the string compare fails.

   Some property values (such as the 'recur' value type), contain commas
   and are not multi-valued.  The CS must understand the objects being
   compared and understand how to determine how any multi-valued or
   multi-instances properties or parameter values are separated, quoted,
