We had the ResourceExistsSelector in the views sitemaps (and some parts
are still using this selector). The FallbackResolverAction is an attempt
to have a cleaner sitemap.

The will try:
1) xdocs/samples/sample.{project:theme-ext}
2) xdocs/samples/{project:theme}.{project:theme-ext}
3) xdocs/{project:theme}.{project:theme-ext}
4) {defaults:view-themes}/{project:theme}.{project:theme-ext}
5) {defaults:view-themes}/{project:theme}.{defaults:theme-ext}

The FallbackResolver is "looping" through the directories downwards till
the last project specific fallback is reached.

How can I implement this recursive looping behavior (1,2) in the lm? The
important part is that the incoming request would be "samples/sample"
for {1}.

This example is missing the looping. Anyway, thanks for giving it. :)
