In certain protocols that make use of &xep0004;, it can be helpful to include XML-data (for example, when we want to insert a big amount of structured data which is hard to insert as a separate fields). This document defines a method for including XML-data in a data form.
-The root element for XML-data is <wrapper/>. This element MUST be qualified by the "urn:xmpp:xml-element" namespace. The <wrapper/> element MUST be contained within a <field/> element qualified by the 'jabber:x:data' namespace.
The <wrapper/> element SHOULD contain an XML-data which needs to be represented in a form.
