Right - a side-effect of the recent changes is to enable getting rid of 
that method entirely because we get the same performance guard in OM 
itself.  There is currently only one usage I can find of 
isHeaderPresent() (in InstanceDispatcher), and I'm about to remove that 
and deprecate the method itself.

Also note that until the DOOM fix I made last night, isHeaderPresent() 
could have returned false in this situation:

1. Create envelope
2. Add body
3. Add header (header is now the *second* element)
4. Call isHeaderPresent()

Both copies [ insert rant here about maintainability of 
llom/doom/soap11/soap12 and how the runtime memory footprint gain maybe 
isn't worth it ] of SOAPHeaderImpl now give you exactly the same 
benefits isHeaderPresent() used to, with the bonus that you get them 
anywhere you use OM, not just in Axis.
