+# Abstract: This will send an application registration message to
+# the xAPP manager.
+#
+# A note about the field descriptions given to j2src programme:
+# They define what we need from the config file. Input to j2src is
+#
+# field:[field:...]:{*|var-name}
+#
+# fields are considered to be an "object" if not the last. The last field may be
+# of the form name[]match=value@pull-name
+# where:
+# the named field is an array of objects and "match" is a field in each
+# object. Each element is tested to see if the match field's value is "value"
+# and when true, the "pull-name" field's value is used. The description is
+# used in our list to pull the rmr-data port from the messageing section.
+#
+# Notes about URLs and DNS names:
+# According to those in the know, the xAPP manager being a platform component will have
+# a fixed DNS name, and thus we expect that.
+#
+# In the less than obvious world of kubernetes we cannot depend on hostname actually being
+# the DNS name for our stuff. So, we assume that if the DN name is NOT the host name, the
+# variable will be set to the DNS name as RMR also depends on this for things.
+# If it's not set, we'll default to hostname.
