(Core Graveyard :: RDF, enhancement)

Build Identifier: 

In Flock, we find it useful to sometimes iterate over an RDF container's elements in reverse order. We've extended the RDF container code to give us that:

http://lxr.flock.com/source/flock/mozilla/rdf/base/src/nsRDFContainer.cpp#L245

If this sounds generally useful, I can cook up a patch against trunk for it.

Reproducible: Always

I'd expect this to be mostly called by js, right?

Sounds like this would be suited for a nice js1.7 generator code snippet, much more than the pretty involved code I found in http://lxr.flock.com/source/flock/mozilla/rdf/base/src/nsReverseContainerEnumerator.cpp

We have a couple C++ users in our tree too.
