How to remove xsi:type attribute ?

[Ge...@nokia.com]

Hi all,


  I'd like to add some header by the means of a hander.
The handler creates some SOAPHeaderElement objects and adds them
to the envelope. My only problem is that in case of using MessageElement
objects and their descendants the xsi:type attribute always gets set.
Calling removeAttribute or setType does not help. :(
I know it can be turned off somewhere in SerializationContext, but
the rest of the message should remain intact. 
 What do you suggest ? I wouldn't want to convert the envelope in 
Document then back to SOAPEnvelope. Is there a good way to handle this ?
Thanx, Geza.
