Description
At today's meeting, the members discussed the following topics:

 1.	TOPIC:  Layers is a useful extension concept, is there a good summary of  the current discussion? (Answer: Three discussion topics related to Layers  include what are Layers, how to implement Layers,  and should Layers be  used in the DE.  Layers appear to be a good concept for enabling  business-level extension, the Layers concept is currently used in CAP
through the use of the Name/Value pairs, and the use of Layers beyond CAP  has been recommended. Norm has uploaded a useful document describing Layers  and their current use with CAP that serves as an informative reference. )

 2.	TOPIC:  Should Layers be implemented in the Common Types? (Answer: The  Common Types is the place to provide schema implementations of concepts  which are expected to be useful across multiple EDXL standards. Since  Layers are expected to be used in other EDXL standards than just CAP, it is  appropriate to consider implementing the Layers concept in the Common  Types. This wouldn?t actually enable Layers in any particular EDXL  standard, it would just provide a common implementation which could be used  to enable Layers in any particular standard if the developers so chose. )

 3.	TOPIC:  If Layers were used in the DE, could it be used to describe  either or both of the overall message and the individual content objects?  (Answer: Yes, it could support both. The DE has descriptive elements for  both the overall message and the individual content objects, so the Layers  concept could be implemented in both places. In the DE draft WD10, it was  used in both places.)

 4.	TOPIC:  How do we help to ensure extension mechanisms like Layers are  not abused? (Answer: We should include extension principles and guidance in  our Note to help alert people of potential issues and how to avoid them. We  can borrow from Norm?s Layers document to describe these principles.)
