First, you can't have dtml in dtml. Period.

Next, when you go to do a dtml-in (AIUI), the objects in the dtml-in are pushed to the front (top?) of the namespace.
sort_key would need to be a property/attribute of the ccDocClass for this to work, and you would just use sort=sort_key.

If sort_key is not a property of the ccDocClass objects, you have to do it some other way. 


UNTESTED HYPOTHESIS:
IF sort_key is in the request space, you _MIGHT_ be able to do
sort=REQUEST['sort_key']. But I am not sure; it's just a guess.
