Oops. I stepped on a touchy point, it seems.

Do you mean from a logical point of view or a rendering point of view? --
From the logical point of view, those are all enumerations, standard math

This is not really what I said; if only math mode is available, one should
either write "see figure seven.three" or "see figure $7.3$", but not simply
"see figure 7.3", as the last is both logically wrong, and invites to
making mistakes in markup.
However, stepping into the question of renderings, one should in this case
have a special label environment, that makes the labels appear
consistently, both logically and in rendering. Again, it should not be
possible to write "see figure 7.3".

So then they should be put in special environments, separating them from

I think that your "textual digits" only arise in the absence of proper
markup, just as it is common to have other symbols sprayed into the text,
in the absence of a proper symbol environments.
