When I try to parse any schema document from the Open Travel Alliance,
I get this error:
mammon:OpenTravel_2007B_PublicReview devin$ python generateDS.py -o
OTA_ErrorRS.py -s OTA_ErrorRSsubs.py OTA_ErrorRS.xsd
Traceback (most recent call last):

AttributeError: SimpleTypeElement instance has no attribute
'attributeGroupNameList'
Does anybody have any idea what this could be related to?
Below is one of the simplest schema documents I could find from the OTA:
