Support header child elements (like payload in message element)

Background

Citrus version: 2.7.1

Problem

There are two ways to write the actual XML message body in a ws:send action :

• <data> which is of type xs:string
• <payload> which allows a arbitrary XML structure

To write the XML SOAP header in a ws:send action there is only <data>. This means that you must always wrap the XML structure in a CDATA tag.
I see no reason why <payload> is not allowed in a <header> tag.

Solution

Allow <payload> as child of <header>.

Example

<!-- Currently this is how you have to define a SOAP message -->
<ws:send endpoint="someEndpoint">
    <message>
        <payload>
            <someXmlStructure>
                ...
            </someXmlStructure>
        </payload>
    </message>
    <header>
        <data>
            <![CDATA[
            <someHeaderXmlStructureEnclosedInCDATA>
                ...
            </someHeaderXmlStructureEnclosedInCDATA>
            ]]>
        </data>
    </header>
</ws:send>

<!-- This should be possible -->
<ws:send endpoint="someEndpoint">
    <message>
        <payload>
            <someXmlStructure>
                ...
            </someXmlStructure>
        </payload>
    </message>
    <header>
        <payload><!-- this is currently not possible -->
            <someHeaderXmlStructure>
                ...
            </someHeaderXmlStructure>
        </payload>
    </header>
</ws:send>
