None in HTML, as there is no such element.

There is no formal limit on the number in an alt attribute, but you are
probably misusing the attribute if you have a large number.  There are,
however, cases where a large number might be technically correct, although
one maybe ought to consider whether the text should be explicit text, in
those cases.

The example I'm thinking of would be a pie chart, where one
might need to list the values for each sector (although not the colours,
and only if a visual user would be expected to look in that much detail).
However, providing the data as an explicit table, would allow the user
to copy it into a spreadsheet, etc.

That's probably a good heuristic for rejecting keyword stuffing, in real
world web pages.
