+## Alternative solution
+
+[Here](http://www.jk.fr.eu.org/ikiwiki/format-escapes-2.diff) is a patch
+largely inspired from the one below, which is up to date and written with
+[[todo/multiple_output_formats]] in mind. "htmlize" hooks are generalized
+to "convert" ones, which can be registered for any pair of filename
+extensions.
+
+Preprocessor directives are allowed to return the content to be inserted
+as a hash, in any format they want, provided they provide htmlize hooks for it.
+Pseudo filename extensions (such as `"_link"`) can also be introduced,
+which aren't used as real extensions but provide useful intermediate types.

+> styling info usially added to such a link is lost. I wonder if it would
+> be better to lose _link stuff and just create link html that is fed into
+> the rst,html converter. Other advantage to doing that is that link
+> creation has a rather complex interface, with selflink, attrs, url, and
+> content parameters.

+### Updated patch
+
+I've created an updated [patch](http://www.idletheme.org/code/patches/ikiwiki-format-escapes-rlk-2007-09-24.diff) against the current revision. No real functionality changes, except for a small test script, one minor bugfix (put a "join" around a scalar-context "map" in convert_link), and some wrangling to get it merged properly; I thought it might be helpful for anyone else who wants to work on the code.
+
+(With that out of the way, I think I'm going to take a stab at Jeremie's plan to use marks which would be replaced post-htmlization. I've also got an eye towards [[todo/multiple_output_formats]].)
