How does one use the info in a filter?

e.g.

in (defun my-block-filter (data backend info))

data is the transcoded block string, and I want to add something to it
based on say the type of block, name and header of the corresponding
block. Is it possible to get to that from the info? Or is this a case
where it is easier to make a custom backend with a function like:

(defun sb-format (sb contents info)) that builds up the output string?

Purpose for INFO in filters is to give access to export options. You
cannot have easily access to the element being exported.

Another option is to use a parse tree filter, or as you suggest,
a custom back-end.
