Yes, it may be a bug in ODL, but I also think that there is something wrong to use such a long relative path.  In that case, the relative path is actually longer than the absolute path!  That said, there is no guidance in rfc6087bis currently, so we may need to let it go this time.

This may be. bug in OpenDaylight that is being tickled.  Ranga is
chasing it a bit.

> Both the old and the new path look valid to me. Even if you can always replace a relative path with an absolute from a YANG validity perspective, changing from relative to absolute paths often *changes the semantics*, so that is not generally safe. In this case, however, they do amount to the same thing (since they both end up going all the way up to the top level container).
