BACKEND
    A string consisting of alphanumeric characters, hyphens, or 
underscores (-_).

At first I thought it may be used as [:export backend=-] and it is the 
reason why I was confused. However I still do not see difference between 
[:export backend -] and [:export backend =-].

I agree, it is intuitive, but it makes formal rules more complicated.

I would prefer to modify code to handle
[:export latex.+ latex=/]
to apply first declaration (content only) to latex and second one (skip) 
to derived backends. Anyway the code requires optimization. Walk through 
parent backends is likely inefficient.

Then I will postpone other questions (mostly unrelated to :export).
