XML document can become a tangible thing that processes and people can pass around and interact with.
On the one hand, an XML document is the payload(e.g. purchase order) of a SOAP message
that gets routed around on the Web services network.
On the other hand,an XML document is the form that somebody uses to approve, or audit that purchase order or submit it.
Now,these two documents are not only made of the same XML stuff, they can
literally be the same XML document.
Let's imagine a sales order flowing through a web services
pipeline in any enterprise. It's an XML document, which is
created with a tool such as InfoPath. The document carries core data
elements -- an item number, a department code. But it also carries
contextual metadata -- for example, a threaded discussion involving
the reviewer,the requester, and the approver. These thing are the
key to understanding how the data got there and what it means.
