+This is the set of requests and responses transmitted between a Citrix Metaframe XP Program Neigbourhood (PN) client and a PN server.
+
+This dialogue was captured by and reconstructed from tcpdump.
+
+Citrix are not well known for documenting their protocols although the DTD may be informative. Note that the pair(s) 0 and 1, 4 and 5, ...
+do not appear to do anything.
