  @param theLowerBound A qualified date param representing the lower date bound (optionally may include time), e.g.
  "2011-02-22" or "2011-02-22T13:12:00Z". Will be treated inclusively. Either theLowerBound or
  theUpperBound may both be populated, or one may be null, but it is not valid for both to be null.
  @param theUpperBound A qualified date param representing the upper date bound (optionally may include time), e.g.
  "2011-02-22" or "2011-02-22T13:12:00Z". Will be treated inclusively. Either theLowerBound or
  theUpperBound may both be populated, or one may be null, but it is not valid for both to be null.
