This Attribute defines the type of temporal extent of the region of interest. A temporal point (or instant of time) may be defined by a waveform sample offset (for a single waveform multiplex group only), time offset, or absolute time.
The following Enumerated Values are specified for Temporal Range Type:
POINT = a single temporal point
MULTIPOINT = multiple temporal points
SEGMENT = a range between two temporal points
MULTISEGMENT = multiple segments, each denoted by two temporal points
BEGIN = a range beginning at one temporal point, and extending beyond the end of the acquired data
END = a range beginning before the start of the acquired data, and extending to (and including) the identified temporal point
