Attached is a script as an example of how this might work. << pageversion.=
php >>

To use it:
- include in your local.php
- remove the comment /* ... */ around the various pattern definitions -- =
be aware this may have side effects for your site, depending on what you =
already do with these

It introduces the following markups:

 ~Text creates a reference to a page with the current page's name plus a =
suffix

 SomePage~ looks on SomePage for a numbered or bulleted list of ~Text =
references and returns the last in the list (if there is no list, it =
returns a reference to SomePage

  {{SomePage~SomeVersion}} is a reference to a specified page

I hope most variations work correctly, such as WikiWord~ and {{free link}}~=
, [[WikiWord~ alt text]] and bulleted lists like * [[~Ver2 alt text]].

I haven't tried alternate languages, but I can see setting a variable that =
tells the script to look for a suffix ~de or ~fr, rather than the last in =
the list.

I also haven't tried doing nested versions (SomePage~Version~ markup) -- =
but I *think* {{SomePage~Version}}~ might work...

And it may be appropriate for some situations to modify the page header to =
insert a reference to SomePage on pages of the form SomePage~Text.

Suggestions and improvements welcome.

Several people have commented about the desirability of a "page=20

knowing where things are at the moment, and following PmWiki
Philosophy #3 I have a tendency not to implement anything until
I have a clear idea of exactly what it's supposed to do.

- is it better to have "fallback pages" or "fallback groups"?
- do we have a clear markup syntax?  John Rankin's proposal
  was using ~ for illustrative purposes--is that the markup we
  want to use?  What things are allowed to follow the ~?
- is there a more descriptive/better term than fallbacks?
- are there any other wiki engines that implement a similar concept that
  we might want to borrow from?

As with most features, if it can be implemented as a separate script
module outside of pmwiki.php or with minor changes, it can happen fairly
quickly. =20
