This looks good, but I don't see the need for two functions. Just

 void setNamespaceSeparator(String sep);

seems to me to be enough: null means disable namespace processing (the
default); non-null means expand names using the specified separator.

However, I wonder whether it's really a good idea to allow apps to
choose the separator. It makes it harder to chain together SAX processes
using things like the Filter.  If one DocumentHandler expects names
separated by # and another expects them separated by !, then they can't
work together without some additional glue. I think consideration should
be given to mandating a specific separator character. It's not obvious
to me what the right answer is here.
