I wanted to include extraOptions for setting x_duplicate_window to some other value than the default. In order to do this I hacked cim.py to add an extraOptions element to the request. I could not see another way to do it.
I'm attaching a modified version of cim.py where I essentially hardcoded an additional element to the request to incorporate the extraOptions setting the x_default_window to 1. Would you like me to submit a proposal for how to incorporate this feature? If so, I will give the matter some thought and try to devise something that is consistent with the rest of the library.
