@tbouron i think the logic now (after last push) does the best thing for
corner cases such as blank string (counts are being set but not acceptable when
"required") and false (also counts as being set). also it's a bit simpler.
can you eyeball and merge? i've tested it with the blueprint at
https://github.com/apache/brooklyn-server/pull/999#issuecomment-423919250 and
it seems to work as expected.---
