You can read a complete element only in the stream.
The stream is opened with an opening tag. The closing corresponding tag will
appears "later" or never.

But I think I can reuse SSAX:make-parser to simply emit SXML for the complete
elements embedded in the stream. The creation of SXML will be nearly a
copy of the SSAX:XML->SXML.

(Thus, my problem is gone, just need coding :)
