Wow, that *is* old!  :-)

The boundary relations weren't in (common) use at the time I wrote that
rule; do we have a way to get the relation values onto the lines?  If
so, then great.  As to whether to deprecate the above, or just remove
it, I have no strong opinions.

Thanks for chasing this up - and I though /I/ was a long way behind with
reading this list!
