Hello Wang,
I am not sure I understood your question correct.
When comparing with RDBMS DDL, the DDL of Tamino is the TSD schema language.
You can create dynamically TSD schemas and issue a define request.
The difference is that it is not an own syntax but it is XML. For human readibility this is bad but for programatical construction this is an advantage.
Best regards
Walter
