Yep, that's the "main url" concept. (I should come up with a better name
though).

Yep -- that's true.  But I need to fix that anyway (for printable pages
etc.).

I was considering this: adding "output sets", so that a set of <out>
blocks are grouped together as a related set.  Then the "main url"
for a page, is the url it appears in that set; regardless of where
it appears for other sets.

makes sense -- but I would suggest turning it into a suffix to the
metadata-name string, internally.  You could for example convert

	<wmmeta name=title value="foo" lang=en />

into a metadata content item with a key (ie. name string) of
'foo.title##LANG=en'  (also a copy called 'this.title##LANG=en' as well),
internally.

Also you would need to keep copies called 'foo.title' (as before).

Sure!  the expansion of the variables is in Main.pm (follow it from the
subst() methods) -- and the wmmeta tags are loaded in NormalContent.pm.
BTW it would need to be added to metatable support, in Metadata.pm as
well.

The metadata loading and subst'ing code is a little messy at the moment
I'm afraid.  For example there's a couple of methods called something like
get_metadata(), where one is for loading from wmmeta tags, and one is for
finding the MetadataContent object, or something like that.  So it might
be a bit confusing.  If you run into trouble, feel free to mail me.  But
go for it!
