I really like this approach and I would buy it. On the one hand, if I
understand correctly, it's a universal solution that doesn't depend on a
particular backend (although, to be honest, I don't see much use for
this beyond LaTeX: maybe in HTML). And, on the other hand,
`:export_template' is an attribute that can be, as you say, very
versatile. With this, in my opinion, it would no longer be necessary to
define two 'pre' and 'post' attributes.

I imagine the value of ATTR_BACKEND (would quotes be necessary?) could
be easily converted to a plist, with code borrowed from
`org-export-read-attribute':

(:export_template "\\begin{myenv}\\n%s\\n\\end{myenv} ... etc. ...")

In this case I would not see it necessary, IMHO. For simple things (of
the begin/end style) there are the special blocks. And for more complex
pre- and/or post- code we have export blocks and export snippets. Since
there is no heading involved here, there would be no danger of the
pre-code leaving with the content of the previous header.

Best regards,

Juan Manuel
