OK, what about

 void startElement(String localName, AttributeList attr,
NameSpaceContext nsc)

NameSpaceContext could be unmutable and thus be reused while unchanged.
I could still remember all parameters since there is only one more at
the end :-) 

The parser would only need to check if the NSC has changed and could
reuse the same object otherwise.
