I also would prefer this kind of interface. Further advantage besides
the improved extensability might be that 

- building a new object seems some overhead at the first sight, 
  but in JAVA also a new String is a new object...

- some computation could be performed on demand only(?) 

- I think it is less difficult to remember the access method names 
  than a more or less unmotivated order of a lot of parameters

- the ElementEvent access methods could be a subset of the DOM access
methods (!)

please do not forget to include the "old" SAX 1 methods in HandlerBase
and call them from the new methods as default behaviour preserving
compatibility at least with applications extending
HandlerBase instead of implementing DocumentHandler. 

All the best,

Stefan
