try:

<dtml-if "_.string.rfind(_['id'], '~') != -1">

BTW in python you can look up single characters in a string by:

<dtml-if "'~' in id()">

id is weird, sometime you need to call it as a function sometimes
(depending on the context) you might not. In any case try both versions if
you get in trouble. It is hard to remember which is which as there is no
real design rational behind it.
