Yes. For instance, 'skin.xrc' contains twelve wxPanel instances, which
beget twelve notebook tabs, and we want a screenshot of each: a total
of twelve annotated screenshots for that XRC file.

I think that's perfectly suitable: graphic numerals on graphics,
corresponding to text numerals in text.

I have no trouble looking up the parks numbered here:
  http://www.stevenspoint.com/parks/parkplan/allparks.html
or finding the "Metal Vent Plug" here:
  
http://www.maesco.com/products/racor/r_spn_intro/r_spn_mar/r_spn_assms/r_spn_assms.html
or figuring out which body of water has greater turbidity here:

I'd like to be able to use wxHTML for this purpose.

I try to write html in a subset of the html subset supported by
wxHTML. For instance, this page:
  http://web.cvs.savannah.gnu.org/viewvc/lmi/index.html?root=lmi
looks fine to me in wxHTML. (There's some problem with UTF-8, but
IIRC that'll be okay in some forthcoming version of wx.)

We don't even need CSS. Plain text is perfectly sufficient.
(And <ol> is just a smart, robust way of generating plain text.)
