 This is a private repository for developing oneM2M xsd files
 
 The default branch will initially contain a "0.80" version of the  files, mathching the 0.8 version of TS-0004
+
+Further work / questions on the schemas is listed here. Many of these need CRs against TS-0004
+
+General
+    Look at the way that IDs are represented in the schemas
+
+\<accessControlPolicy\>
+
+    Do we need to give explicit names to all the types currently defined in the file?  
+    Should some or all of theses types go into CDT-CommonTypes or CDT-Enumerations?
+    Since accessControlOperation is an enumerated integer type, we could represent accessControlOperationList as a   list of simple types. This would be shorter than having it as a complex type.
+    Look at definition of accessControlOriginators
+
+\<container\>
+
+    What values go in latest and oldest if there are no child resources?
+    Should <containerAnnc> be allowed to have <contentInstanceAnnc> as a child resource?
+    
+\<subscription\>  
+
+    Should the eventNotificationCriteria type be moved in to Common Types? (i.e. is it used anywhere else?
+    
+CDT-enumerationTypes
+
+    Add or update definitions of the following types:
+      resultContent, statusCode, requestStatus, attribute, notificationCongestionPolicy
+    Does m2m:memberType need to be different from m2m:resourceType? Can we remove it?
+    Sort out the two m2m:operation types
+    Better name for listOfBoolean (it isn't a list)
+    
+CDT-commonTypes
+
+    General revision and checking required (defer this until after the other XSD files are complete)
+
