[THREDDS #WOQ-367016]: Unexpected Behavior and Questions About the (beta) TDS 5.0

Hi Nathan,

Thanks for posting those! We'll take a look and see what we can get done
here. FYI - we are aiming to have an official v5 beta out at the beginning
of November, and these kinds of issues will get ironed about before then
(ideally, way sooner).

Thanks for your feedback!

Sean
