It would be lovely if there were markup for making ordered/numbered lists start
from an arbitrary number. Currently, it is doable via html, but it would be nice
(and shorter to write) if there were something like:

#|123| Item1
#Item2

which would render html like this:

<ol start="123">
<li>Item1</li>
<li>Item2</li>
</ol>

Of course, different markup (prone to backwards compatibility) can be used.
