I've just fixed one bug that may have caused this.

To dynamically generate grammars, you need to:

 - call the cocoon:/wiki.{xgrm,xlex} pipelines instead of the static
 - Uncomment the *.xgrm and *.xlex pipeline definitions

Both done in forrest.xmap.  Attached is a diff for forrest.xmap showing
how it's done.

If you're planning on doing any serious work on the grammars, there are
some issues to be aware of.  The grammars were taken from Cocoon's
chaperon sample block,  However, they are not the same as those in Cocoon
now.  Cocoon's Wiki grammar seems a bit more advanced, but has some bugs
that, being lazy and chaperon-ignorant, I didn't feel like fixing at the
time.  Forrest's wiki.grm log says:

revision 1.3

Revert to the 20030311 Wiki grammars, as the CVS HEAD versions don't seem to
recognise subtitles.  The new wiki2document softbreak template seems to have
fixed the whitespace problems.
