XML Support
What kinds of XML do messages support?
This isn't a simple question because, like many parts of a framework, it's important to distinguish what could possibly be done given enough time versus what could easily be done given the components that ship in the box. With the components that ship in the box, you can read and write XML 1.0 documents plus the binary XML format that we include as well. All of this support is through classes for defining XML readers and writers. You can define your own readers and writers with this model. For example, it should be possible to build a message implementation that supports XML 1.1 documents, although I have never tried this to see if it would work. You can even work with documents that are not recognizable as XML in any form using the same approach as long as there is some way to project that external document to an XML InfoSet temporarily during message processing.
