The appended patch allows for custom layouts of the exported XHTML. As
the custom elements are added literally, PHP code could be added too.

Everyone who's informed about my elisp skills will read this with
appropriate scepticism :)

It's merely a proof of conncept, a suggestion.
Maybe we could find a more `template' based solution to make this easier
on non-lispers.

I didn't implement all the containers mentioned in the docstring of
`org-exp-custom-html-function' yet, but it's just adding two lines per
block.

If you add this patch, you'll be able to do the following:

1.) Define a function that add custom HTML elements.

    This example will produce a table layout with the TOC on the left,
    contents on the right. Title and postamble will span both columns.

    (defun sr-org-export-custom-html(which &optional element-start)
      "See the docs of org-exp-custom-html-function"
      (cond
       ((string= which "body")
        (if element-start
            "<div id=\"wrap\">"
          "</div><!-- end of wrap -->"))
       ((string= which "title")
        (if element-start
            "<table width=\"100%\"><tr><td colspan=\"2\">"
          "</td></tr><tr><td>"))
       ((string= which "toc")
        (if element-start
            ""
          "</td><td>"))
       ((string= which "postamble")
        (if element-start
            "</td></tr><tr><td colspan=\"2\">"
          "</td></tr></table>"))
       ))

2.) Add a line to your `org-publish-project-alist'.


        ("org-notes"
         ;; ....
         :publishing-directory "~/develop/htdocs/org-notes/"
         ;; Tell org-exp.el to use a custom function:
         :publishing-function org-publish-org-to-html
         ;; ....

3.) Apply this patch to the current head:

This looks interesting.  Do you have application examples?

A more template-like structure would be an alist, with contexts as keys,
and then two string values for the code to be inserted.  Using  
customize, this
could be set up by non-lispers.

Only the one I mentioned in the original message so far. It just wraps
the hole page into a table like this:


  +--------------------+
  | Title              |
  +-----+--------------+
  | toc | sections..   |
  |     |              |
  |     |              |
  +-----+--------------+
  |     postamble      |
  +--------------------+



But I can think of hundreds of applications:

  * It would be easy to add a logo to the title bar,
  * or some debug information to footer for local testing.
  * But no such debug info for the public export to the internet.
  * you're google search on orgmode.org
  * some PHP-functions one might want to execute, e.g. to include
     + a tag cloud
     + additional navigations
     + count visitors
     + track the movement of visitors
     + include a shop system  - just kidding :-D
     ...
  * Clean view of the *.org files. No more
       #+begin_html
         ...
       #+end_html
    or
       @<ul class="external-menu"....
    to include standard stuff, common for all pages.
  * TODO: add the 94 missing applications here


Maybe the settings could be augmented/overwritten on per file basis too?
