how to determine files missing certain propertiers?

Hi all,

I'm trying to find files missing certain properties either locally in
a WC, or remotely in a repository.

I've experimented with scripting 'svn list' and 'svn propget' but that
didn't work out because of my missunderstanding of what this commands
really do (see threads "discrepancies between 'svn -R list' and 'svn
-R propget'" and "svn --recursive and externals").

So, anyone out there with solutions/hints/links?
