By attaching semantic actions to various points in this hierarchy, in effect we can transform the flat linear input stream into a structuredrepresentation.
借由将语义动作黏附到这个层次中的很多黏附点上，我们可以将平滑的线性输入流转换成结构性的对象。

The implementation might actually process the DTD into a more structuredrepresentation (which is provided-specific) and make it available by calling the getProcessedDTD() method.
Whenever you try to query a spatial column, DB2 injects a transformation from the internal, structured type representation to a representation that can be understood by the application.
