Updated Extension Proposal

CTI TC -

Please find attached an updated STIX extension proposal that the mini-group worked with IBM (Jason/Emily) to incorporate an acceptable compromise to their concerns.

In summary:

1) Previously presented extension proposal is maintained and has been named âsub-component extensionâ to clarify the distinction between when it would/should be used vs the additional mechanism added for top-level extension.

2) Added the concept of Top-Level object extension to allow extension properties directly with existing STIX standard objects.

3) Clarified language/definitions around use for both aspects.

The google doc containing the specification changes are here:

This proposal represents the agreement by all mini-group participants. We would like to encourage the TC to consider this proposal and incorporate the changes to the STIX standard.
