support of CMOF:DataType by infrastructure

[vadim.godunko]

Several extensions should be done to support CMOF::DataType:

• module's factory should specify the way how to operate on structured data types;
• XMI reader/writer should be able to handle structured data types;
• code generator should be extended to generate appropriate code as much as possible.
