No problem at all.  This is totally understandable.

Yes, it would be nice to have a generic exporting framework in Org.
When I just started working on the DocBook exporter, I tried to follow
org-export-latex.el first but hit some limitation in org-list-to-generic
after a short time.  Then I switched to the style of org-export-as-html,
and found its line-based exporting very easy to use.

I haven't read about this, but I can imagine what kind of difficulty you
might have...

Agreed.  If Org documents can be parsed into tree representations by the
generic exporter, and each individual exporter only needs to configure
the tags (or formatting methods) for all components in the tree, writing
different exporters would be much easier.  Not sure if this can be
easily done in Org.

Yes, DocBook exporter is heavily based on the XHTML exporter.  Both
exporters shares a lot of processing, but differ at other areas.  Some
internal functions used by these two exporters could be merged in the

Thanks a lot for making the changes in org-exp.el!  I've removed the
modified version of org-exp.el from my repository on Google Code.  I'll
try to do more testing (including testing it on XEmacs) and incorporate
any comments that other people may have before you can put this exporter
into Org release.

I won't have any problem with maintaining this exporter.
