[j-nsp] BGP no-export community behavior special?

I'm testing some BGP policy changes, and I'm running into an odd thing.
There are some routes that I don't want to export in general, but I do
want to send them to a couple of specific eBGP neighbors.  For these
routes, I've got an import policy that adds the no-export community.

First, it appears that routes with the no-export community are
automatically not exported to eBGP neighbors - that makes sense, but I
didn't find that behavior documented anywhere (so my policies were
explicitly rejecting no-export routes).

It seems though that I can't strip the no-export community with an
export policy.  Is that expected?  Is JUNOS not even passing no-export
routes to the export policy for processing?
