> The problem is with the last rule:

> ("\"" (0 (if (prog1 (zerop (car (syntax-ppss (match-beginning 0))))
>                     (goto-char (match-end 0)))
>                   (string-to-syntax ".")))
> ```
> I can't see the real effect of this rule, I tested xml parsing without
> this rule and it works fine, marking double quotes inside tags as
> expected without this performance issue.
> Do we need to target double quotes outside tags explicitly?

Stefan, any comments?
