Ruwan Linton commented on ESBJAVA-559:
--------------------------------------
Kevin, according to the SOAP11 and SOAP12 specifications it is not possible to
have headers without namespaces, in other words each and every SOAP header
block has to be namespace qualified.
There is an issue in the Header mediator, which allows you to add SOAP headers
without namespaces and it has to be fixed. There is a JIRA for this already in
Synapse. Please refer to https://issues.apache.org/jira/browse/SYNAPSE-345
