This is an ambiguous headline. Indeed, it's impossible to tell if it is
an empty headline with tags or a headline without tags whose title is
":B_block:BMCOL:".

I think the last option is better as the first one prevents any
headline's title from being enclosed within colons. This is restrictive.

 

That probably makes sense, though I still feel it is a little inconsistent. One could argue that anything within colons is an org tag (regardless of whether the title is empty), and isn't meant to be exported. It's probably rare to start a headline with a colon anyway. 

Plus, I guess you are still somewhat restricted if you want to export a headline ** foo :bar:, where :bar: is not a tag. ;)

In any case, there are workarounds available for what you have to do.

Yes, either way works.

Thanks,
