Comment 5 for bug 1278090

It is a bug, but it isn't really all that important.

Excerpts from Amit Ugol's message of 2014-02-11 05:38:05 UTC:
> I opened this bug thinking that empty templates should not be validated as they create 'bad' stacks but then I saw the validation thing (as posted) and added that to the description as well. I know empty templates are YAML valid but IMO that does not mean that they are 'heat valid' as in heat will not be able to do anything with them, rendering them useless.
> If needs be I can just open a different one for 'validation only'.
