I don't think that code can be correct. You are assigning an int to a
T2Reference.

You do not need to check that the depths are compatible. The "depth" of
the T2Reference will be the depth of the input port.
If the service is expecting a single value and you pass a list, then the
Taverna engine will call the service for each element of the list. If
the service expects a list and you pass it a single value then Taverna
will wrap the single value in a list.
Can you give an example of what you want to check?
