Yeah. Extra matcher is probably too cumbersome.
Yet, I feel like conditional prefix/suffix may be useful in some
scenarios.

Having read the available replies in this thread, I am thinking of the
following:

1. Instead of explicit prefix and suffix, we can unify extra text around
   the exported Org element to a template:

* headline
:PROPERTIES:
:ATTR_BACKEND: :export_template "\begin{myenv}\n%s\n\end{myenv}"
:ATTR_BACKEND+: "The %%s instances are replaced by the exported element"
:ATTR_BACKEND+: (concat "arbitrary sexp, the exported element is bound to: " 
*this*)
:ATTR_BACKEND+: babel_block_name(exported=*this*)
:ATTR_BACKEND+: "the property lines are concatenated with \" \" (space),"
:ATTR_BACKEND+: "just like the usual approach in `org-export-read-attribute'"
:END:

#+ATTR_BACKEND: :export_template "can also work on non-headings"
Paragraph.

2. The generic Org export routine will remove the :export_template
   attributes prior to passing the element to backend-defined export
   transcoder, thus avoiding the problem Max raised wrt ox-html
   attributes.

3. Similar to :export_template, we can have
   :export_prefix/:export_suffix, but I feel that the template will be
   more flexible.

WDYT?
