+#  Stan Smith 2018-01-10 added reference system WKT
 #  Stan Smith 2017-10-23 added reference system parameter set
 #  Stan Smith 2016-10-16 refactored for mdJson 2.0
 #  Stan Smith 2015-07-14 refactored to remove global namespace constants
 #  Stan Smith 2015-06-22 replace global ($response) with passed in object (responseObj)
 #  Stan Smith 2014-12-15 refactored to handle namespacing readers and writers
