A very good point. However, I think the sort of exception you're 
describing is only a truly exceptional exception such as an I/O error 
like a broken socket or an out of memory condition. I'm not sure a 
malformed document qualifies as exceptional in this context. There's 
no reason, after all, the parse method has to throw an exception to 
indicate malformedness. It could easily have returned a boolean 
indicating whether or not the document was well-formed. Not that I'm 
suggesting such a change at this late date, of course. I just want to 
point out that there are other ways to design such an API that don't 
rely on exceptions. In practice I encounter malformed documents far 
more often than I/O errors, out of memory errors, and similar 
problems. They just don't feel that exceptional to me.
