Change the replacement punctuation from "[id]" to "-.id.-" or ":-id-:" or
something like that. This has two advantages:

   a) The combination of that very unusual punctuation sequence (both
      opening and closing) /and/ an exact match of the template ID is
      going to be so rare as to be practically ignorable.
   b) ID and NAME attributes using the replacement mechanism can still
      be valid.
