----------------------------------
[~reta] That interceptor coming into picture when we configured
{color:#2a00ff}org.apache.cxf.feature.StaxTransformFeature{color}
to map namespace mappings in cxf bus like this:
_{color:#008080}<{color}{color:#3f7f7f}bean{color}
{color:#7f007f}id{color}={color:#2a00ff}"nsTransformFeature"{color}

Without these mappings, that interceptor is not getting added into interceptor
chain and everything just works.
When i looked at code of {*}TransformInInterceptor{*}, found this:
_{color:#7f0055}public{color}{color:#000000}
{color}{color:#7f0055}void{color}{color:#000000} handleMessage(Message
{color}{color:#6a3e3e}message{color}{color:#000000}) {{color}_
_{color:#000000}{color}{color:#7f0055}if{color}{color:#000000}

== {color}{color:#7f0055}null{color}_
_{color:#000000}||
MessageUtils.{color}{color:#000000}getContextualBoolean{color}{color:#000000}({color}{color:#6a3e3e}message{color}{color:#000000},
{color}{color:#7f0055}this{color}{color:#000000}.{color}{color:#0000c0}contextPropertyName{color}{color:#000000},
{color}{color:#7f0055}false{color}{color:#000000})) {{color}_
_{color:#000000}XMLStreamReader
{color}{color:#6a3e3e}reader{color}{color:#000000} = (XMLStreamReader)
{color}{color:#6a3e3e}message{color}{color:#000000}.getContent(XMLStreamReader.{color}{color:#7f0055}class{color}{color:#000000});{color}_
_{color:#000000}InputStream {color}{color:#6a3e3e}is{color}{color:#000000} =
(InputStream)
{color}{color:#6a3e3e}message{color}{color:#000000}.getContent(InputStream.{color}{color:#7f0055}class{color}{color:#000000});{color}_
_{color:#000000}XMLStreamReader
{color}{color:#6a3e3e}transformReader{color}{color:#000000} =
{color}{color:#7f0055}this{color}{color:#000000}.createTransformReaderIfNeeded({color}{color:#6a3e3e}reader{color}{color:#000000},
{color}{color:#6a3e3e}is{color}{color:#000000});{color}_
_{color:#000000}{color}{color:#7f0055}if{color}{color:#000000}
({color}{color:#6a3e3e}transformReader{color}{color:#000000} !=
{color}{color:#7f0055}null{color}{color:#000000}) {{color}_
_{color:#000000}{color}{color:#6a3e3e}message{color}{color:#000000}.setContent(XMLStreamReader.{color}{color:#7f0055}class{color}{color:#000000},
{color}{color:#6a3e3e}transformReader{color}{color:#000000});{color}_
_{color:#000000}}{color}_
_{color:#000000}}{color}_
_{color:#000000}}{color}_
This logic setting XMLStreamReader to Message.
