What is the WordOpenXML property for?
I've been experimenting with building an Outlook 2010 addin in C#, using Visual Studio 2008.  I am able to obtain a `Microsoft.Office.Interop.Word.DocumentClass` object from a `Microsoft.Office.Interop.Outlook.Inspector` object, which represents the e-mail being currently edited.  I understand that this `DocumentClass` is used in various other contexts too (usually for Microsoft Word extensions, unsurprisingly).

That class has a property called `WordOpenXML`.  Looking on the web it seems to be a string of XML representing a collection of 'packages' representing all the things connected to the current document, including obviously its content.

What I'm interested in are my options for converting this into other formats, or how this property is useful at all.  I haven't been able to find anything really about even converting this string to a .docx file, let alone converting it to some other format.  Seeing as it should contain all the information about the current document, shouldn't it be possible to convert it into various common file formats representing that document?  Does anyone know how to?  If not, what is it good for - why is it there at all?  It seems to be read-only so you can't edit the document through it.
