OK, much as I'm loath to propose new tags from past experience on the
list, here's some suggestions.

1) New network, new tags

national_byway = yes / proposed / loop / loop_proposed

The loop is for the "50 circular loops" that they mention on their
front page. At http://www.thenationalbyway.org/loops.asp it suggests
they are signed separately, so it's probably worth making the
distinction when tagging.

2) Crowbar into existing ncn tag

Rather than use the ncn_ref tag, use the ncn tag. ncn then becomes

ncn = yes / proposed / national_byway / national_byway_proposed /
national_byway_loop / national_byway_loop_proposed

I'd prefer 1) myself, since it's clearer to me and much, much easier
to deal with! I know there are a few people who object to creating new
tags, which I don't understand, but that's why I make both

Let me know which option you pick, and I'll get it into this week's map.

When it comes to free-text names of routes, I'd suggest tacking on
_name to the relevant tag, in the same way that _ref is tacked on to
different things. So your Oakham Loop is then either:

1) national_byway = loop , national_byway_name = "Oakham Loop"
2) ncn = national_byway_loop, ncn_name = "Oakham Loop"
