XML handling Type Trees versus Schema

It is generally recommended to use XSD meta data inside ITX when the format is XML (rather than native ITX type trees). This is even more important for WMB integration since it allows closer binding to the WMB XMLNSC domain which is more efficient. However, in some circumstances the XMLNSC binding could be unsupported so the integration flows must support both the BLOB and XMLNSC domain for the ISF bindings.
