Simple Types

There are 44 built-in XML Schema types. Table 4 illustrates how HydraExpress maps XML Schema types to Standard C++ Library types and SourcePro C++ types.

NOTE: 	 By default, HydraExpress links to Standard C++ Library types. To link to SourcePro C++ types, use the -sourcepro option when invoking the code generator.

For the SourcePro C++ classes in the table below, please refer to the SourcePro documentation for descriptions.

¹ For duration, the mapping is to a HydraExpress Library class because there is no good equivalent in SourcePro.
