Preparing for WD03

All,
The editors (Drew and I) are just about done incorporating all of the suggestions from WD02. There are two sections specifically I would like to call your attention to:
1)  5.7 Delete an Obejct
This endpoint defines how a client can request that the server delete an object from a collection. NOTE: this is not a STIX Revoke.  This is just simply removing the existence of an object or version of an object from  a collection.
Some text I would like to really consider is: "  When  a TAXII Server deletes an object from a collection, it
MAY
remove it just from that collection or remove it from all collections and any internal store."
We also need to make  sure we have the HTTP Status Codes right for this DELETE endpoint.
2) 5.8 Get Object  Versions
This endpoint allows  a client to easily just get the versions of an object that the server has. This is a very simple endpoint. But please review.
Thanks
Bret
