Personally I would go for a more generic policy structure. I like the concept overall, I would just push it one level of abstraction higher. Markings are just one kind of policy statement.
Thank you.

That is a good option too. I do like the idea of doing some sort of client / server negotiations.

My proposal was that it would be on the TAXII collection, not the objects.
required_markings="TLP" on a collection means that every object submitted must contain a TLP marking, if it does not, it is rejected.

Is the intent that these properties live within TAXII or on the STIX objects themselves?

All,
It has been proposed that we add some properties to collections to help identify what data markings are needed / supported in this collection. One driving aspect is with the upcoming IEP policy stuff.
It has been proposed that we add something like the following two properties:
supported_markings
required_markings
The property terms may need to be word smithed and we need to figure out how to best capture the data. But the question right now is, should we support this functionality on collections?
If so, I will add them to the TAXII 2.1 working specification so that we can being work on what they will mean.
