No description provided.

I'm interested in merging this PR with refinements:

• Document all the supported values
• Validate that only "exact", "better", "minimum" and "maximum" are accepted
• Include automate test coverage to illustrate it works as expected. You can refactor related code to make it easier to unit-test this if needed.
• When done, rebase and squash the work into a single commit.

I reviewed the spec and found this feature and the supported value documented here confirming that this chang e would improve our spec compliance.

I've merged this, but renamed comparisonType to RACComparison, as comparisonType is too generic. I also documented in the main README.
