Thanks!

I do not think that CSL limitations are really limiting us.

- Allowing macros will be handled by ox.el itself automatically
- Export snippets can also be processed without much issue (consider
  direct LaTeX code)
- inline-babel-call and inline src blocks may be useful with :exports
  results when some auto-generation of text is needed. They will also be
  handled automatically by ob-exp.
- latex-fragments are either equivalent to direct LaTeX or to inserting
  an image
- timestamps could be exported as text, although I do not see any
  obvious utility of timestamps inside references.

However, oc-csl should not ignore the export processor to support all
the above. I am not sure why you need a dedicated export processor
instead of passing the string to current processor (or derivative)
instead.

If you really need to mark certain constructs specially for CSL, you can
create a derived export backend for the current backend and replace the
transcoders for the object types that must be treated specially.

Why :name, but not :html?
