Yes, That is right. If we wrote handler
which get parser and insert filter,
at the top of handler chain, then we
could avoid to change transport layer to 
insert filter.

But we can not filter SOAP header part
by the handler solution, because
SOAP header part is already build in
transport layer before handler layer
by invoking envelope.getBody(). For
example, envelope.getBody() is called 
on the bottom of HTTPTransportUtils.processHTTPPostRequest(),
then the envelope
is passed to AxisEngine. All StAXEvents
of the SOAP header are already consumed 
by the handler gets envelope.
