Could this mechanism be used for other types of queries, too? Would be
nice if this filter mechanism could replace access checks like this:

  #if($xwiki.hasAccessLevel("view", "${context.database}:${item}"))

Sometimes what you want to exclude varies from place to place. Seems
like a way to specify an arbitrary document with a PageFiltersClass
object would be a way to solve that issue.. (I assume you meant it,
and I just didn't read it that way).
