Hi Bob,

I've CC'ed xsde-users at codesynthesis.com to my reply in case someone else
has a similar question one day.

With C++ exceptions disabled, the error handling is performed with error
codes. For more information on error handling with codes during parsing,
see Section 7.3, "Error Codes" in the Embedded C++/Parser Mapping Getting
Started Guide:

http://www.codesynthesis.com/projects/xsde/documentation/cxx/parser/guide/#7.3

For the same during serialization, see Section 8.3, "Error Codes" in the 
Embedded C++/Serializer Mapping Getting Started Guide:

http://www.codesynthesis.com/projects/xsde/documentation/cxx/serializer/guide/#8.3

Finally, if you modify the C++/Hybrid object model, there could be memory
allocation errors. For more information on handling these, see Chapter 4,
"Working with Object Models" in the Embedded C++/Hybrid Mapping Getting
Started Guide:

http://www.codesynthesis.com/projects/xsde/documentation/cxx/hybrid/guide/#4

There is also the 'minimal' example in the examples/cxx/hybrid/ directory
of XSD/e distribution that shows how to use error codes for all of the
above operations.
