hey @sneivandt, apologies for the late response. these changes look good overall!
mind rebasing off latest master to resolve the newly created file conflicts?

Jenkins, please test this

[talevy]

@sneivandt thanks for the rebase. think you can add tests around this for parseDocs? either in the rest-spec tests or simulate unite tests

other than that, changes look good!

Hi @sneivandt sorry for the late response. I see you added tests (that I missed) Think you can rebase off the latest changes so that we can continue with your PR?

[sneivandt]

Hey @talevy take a look now. Should be up to date.

[talevy]
