OK.  Thanks for your through clarification.

This happens with the patch (as is does with divs ATM).

So you want it to be section until h:N?  That should be easy.

As you prefer.

Thanks.

OK.  That certainly makes it easier.  But should it not then be a cons
or an alist specifying which container to use when the headline level
is above or below h:N and deepening on whether html5-fancy is used?

So blogs, technical docs and similar?  I can see people using Org such
things?  Or do W3-people thinkg of something different when they say
it is "syndicatable"

I can change my patch to this behavior if you want.  Though I think
it's pretty strong to hardcode values, as one would might have reasons
to change it in say an ox-publish project.

Good point.

Thanks again Rick.
