  * By default the xpath expressions should simply be checked for existance
  * The xpath expressions can point to elements or attributes.
  * 
  * The array values can contain a number of items, which alters the query
  * filter. 
  *
  * * time-range. Must also check if the todo or event falls within the
  *               specified timerange. How this is interpreted depends on
  *               the type of object (VTODO, VEVENT, VJOURNAL, etc)
  * * is-not-defined
  *               Instead of checking if the attribute or element exist,
  *               we must check if it doesn't.
  * * text-match
  *               Checks if the value of the attribute or element matches
  *               the specified value. This is actually another array with
  *               the 'collation', 'value' and 'negate-condition' items.
  *
