Documentation for vocabulary values

[samwagg]

Sometimes the meaning of CTIM vocabulary values isn't self evident. For example, there are many types of Observable Object, and at least some of them are potentially esoteric or ambiguous. A recent example is processor ID, which I think is an x86-specific hex number that identifies an x86 processor model.

STIX documentation includes descriptions for all vocabulary values. It would be ideal if CTIM had a way to attach (optional) documentation to each value too.

• Explore options and propose a solution for feedback from stakeholders
• Implement solution. No need to add many descriptions now. The idea is enable the ability to add descriptions so it's possible to enrich docs going forward.
