Interesting. If you are generating templates in a CMS that will then be
used to generate the final pages, though, what I would do would be to
generate the template parta with a placeholder character (U+001A) instead
of an ID (note that that character cannot ever be a legitimate character
in an HTML document). Then, search that generated string for the regexp
/\[t([0-9]+)\]/, taking note of the highest numeric match for that
embedded pattern (basically, this is searching for strings like "[t12]",
for all values of "12"). When you know the highest number that matches
that, increase it by one, and use that in the template of the ID ("t13"
or similar). Then, replace all occurances of the placeholder character
with that ID surrounded by square brackets.

It sounds complicated but it's only a few lines of code.

The case I would be more worried about is simple cases where the template
is largely fixed with just one or two attributes getting values from the
user (e.g. an <img> element's src="" attribute in the template having
its value come from the user's config).

I don't think so. You can easily do something like that though:

   <input type="range" oninput="title = Math.pow(2, value)"
          min="1" max="10" ... >
