All, When we added the TAXII envelope to working draft 04, we said that the `data` property should contain a STIX `bundle`. Now that I have code written for it, I think this is a mistake. What this gives us is two useless layers. I think it would be much better to say the `data` property in the TAXII envelope is just a list of STIX objects, instead of saying that it is a STIX Bundle that has an objects property that is a list of STIX objects. So in a nutshell we have: { "more": false, "data": { "type": "bundle", "objects": [ ...list of stix objects ] } } What I would suggest we do is: { "more": false, "data": [ ...list of stix objects ] } This make things cleaner and easier to work with in code. I would like to hear from people that either support this or are against it. If you are against it, I would like to understand why. The plan would be to make this change in Working Draft 06 after the Public Review Period. Thanks Bret
