<dtml-let criteria=="'1=1'"> should work.

In dtml-let, you write one pair of quotes to specify that your're writing a
python expression. Inside quotes you're writing python.

Examples of valid python expressions:
   'this is a string'
   23
   methodname

You can wrap up any of the above inside a pair of double quotes and then use it
in <dtml-let>
