Well I think I'm tracking this stuff down little by little. It looks like {0}
represents the
*entire* matched value (minus the path).
So, for example, if the match pattern was "*.xml" and the URL was
http://foo/bar/simple.xml, then
{0} would equal "simple.xml".
I'm still trying to figure out from my first example why has {../0} and {../../locale}
when it
seems like they should be at the same level... I'll report the results of my findings
if I find
any after some more trial & error in the hopes that it will help somebody else.
