Currently file externals *must* always be from the same repository, because they are just switched files with a bit of special UI on top of them. (See the original introduction text of file externals)

We didn't fix this limitation for WC-NG yet, even though we should be able to describe a new working copy for just a file. (An issue would be that we can't use the normal update editor to describe changes on just a file, but that is easy to work around)

I think you can assume that for a file-external no unswitched BASE_NODE exists, while for a normal switched path there most likely is a BASE node.
