[xsde-users] Serialization crashes for data model constructed from
multiple xsd files

I am experiencing a strange crash in the serialization that I am attributing to the fact that my data model is defined in 2 separate xsd files. My first file <SignalManipulationModel.xsd> contains a set of object definitions which is used by multiple other xsd files. My second file <SignalOperationModel.xsd> includes the first to define some additional data structures and a root element. I have an xml file that is constructed using objects in the second schema file. I am trying to parse this xml file, inspect the resulting data model, and then serialize it back to the screen. Parsing works flawlessly and inspection of the data model shows that all the data is in order. When I attempt serialization, I get a hard crash with unhandled exception - access violation. The crash happens in <elements.ixx> in the serializer_base::_set_type method.
If I move all the definitions to a single xsd file, the problem goes away. This is a little help to me since these schema files will eventually be auto-generated from a third party software, and I cannot force it to only use 1 xsd file. I am attaching the schema files, the xml file and the c++ code segment that illustrates the problem. Any idea is much appreciated.
