Re: [cti] Update from STIX Package renaming Mini-Group

Here you go....

Currently you can apply the data markings at the package level and have them inherit down to the all the objects in the package.  

{
  "type": "package",
  "id": "package--5e2cb95f-30c1-46d3-8b39-d97d34d82d3c",
  "created_by_ref": "source--5e2cb95f-30c1-46d3-8b39-d97d34AAAAAA",
  "created_time": "2016-04-29T14:09:00.123456Z",
  "revision": 1,
  "modified_time: "2016-04-29T14:09:00.123456Z",

  "object_marking_refs": ["marking-definition--089a6ecb-cc15-43cc-9494-767639779123"],
  "spec_version": "stix-2.0",
  "indicators": [
    {
      "type": "indicator",
      "id": "indicator--8e2e2d2b-17d4-4cbf-938f-98ee46b3cd3f",
      "created_by_ref": "source--f431f809-377b-45e0-aa1c-6a4751cae5ff",
      "created_time": "2016-04-29T14:09:00.123456Z",
      "revision": 1,
      "modified_time: "2016-04-29T14:09:00.123456Z",
      "title": "Poison Ivy Malware",
      "description": "This file is part of Poison Ivy",
      "pattern": "file-object.hashes.md5 = '3773a88f65a5e780c8dff9cdc3a056f3'"
    }
  ],

  {
    "type": "marking-definition",
    "id": "marking-definition--089a6ecb-cc15-43cc-9494-767639779123",
    "created_time": "2016-02-19T09:11:01Z",
    "definition_type": "tlp",
    "definition": {
      "tlp": "GREEN"
    }
  }
}

What we are proposing is just putting the reference on each TLO instead of trying to "inherit" it from the Bundle / Package. 

{
  "type": "bundle",
  "spec_version": "stix-2.0",
  "indicators": [
    {
      "type": "indicator",
      "id": "indicator--8e2e2d2b-17d4-4cbf-938f-98ee46b3cd3f",
      "created_by_ref": "source--f431f809-377b-45e0-aa1c-6a4751cae5ff",
      "created_time": "2016-04-29T14:09:00.123456Z",
      "revision": 1,
      "modified_time: "2016-04-29T14:09:00.123456Z",

      "object_marking_refs": ["marking-definition--089a6ecb-cc15-43cc-9494-767639779123"],
      "title": "Poison Ivy Malware",
      "description": "This file is part of Poison Ivy",
      "pattern": "file-object.hashes.md5 = '3773a88f65a5e780c8dff9cdc3a056f3'"
    }
  ],

  {
    "type": "marking-definition",
    "id": "marking-definition--089a6ecb-cc15-43cc-9494-767639779123",
    "created_time": "2016-02-19T09:11:01Z",
    "definition_type": "tlp",
    "definition": {
      "tlp": "GREEN"
    }
  }
}

Can we get examples for the open question on markings?
