# ISO <<Class>> EX_TemporalExtent
# writer output in XML

# History:
# 	Stan Smith 2013-11-15 original script
#   Stan Smith 2014-06-03 add support for date as time instant
#   Stan Smith 2014-07-08 modify require statements to function in RubyGem structure
#   Stan Smith 2014-12-12 refactored to handle namespacing readers and writers
#   Stan Smith 2015-06-22 replace global ($response) with passed in object (responseObj)
#   Stan Smith 2015-07-14 refactored to make iso19110 independent of iso19115_2 classes
#   Stan Smith 2015-07-14 refactored to eliminate namespace globals $WriterNS and $IsoNS
