+# GOAL
+
+* Confirm whether eventual integration of pcap and pcapng into same project, without collisions, makes sense from a long-term DFDL perspective.
+
+# TODO
+
+a. Can pcap.dfdl.xsd and pcapng.dfdl.xsd coexist in same directory?
+
+b. Note changes to binaryDynamicByteOrder.dfdl (which should be compatible)
+
+c. Any other version differences?
+
+d. Keep pcap and pcapng in same directory?
