    core: Use namespaces from all entries in a feed
    
    We were previously assuming that all entries in the feed had identical sets
    of namespaces, and just using the namespaces from the first entry. This can
    be untrue for batch feeds, so we must use the namespaces from all entries in
    the feed.
