UBL and Microsoft Word / Excel + Open XML SDK?

["David RR Webber \(XML\)" <david@drrw.info>]

This looks like you could build a tool to have end users create Invoice
in MS Word - and then place that document in the "Send" folder of
something like the S2Sclient on the desktop - and have it package the
Word content as a valid UBL XML transaction and send it via ebMS....

Open XML SDK: Tech Preview
Brian Jones, Blog

"Microsoft announced the release of an early preview of a managed API
for the Open XML formats, available for download as a Community
Technology Preview.  This is another tool that will help make it easier
for developers to build solutions on top of the Office file formats.
The easier we can make it for people to build solutions, the more
valuable the documents themselves become. This is a very early preview
and we're hoping to get a lot of great feedback to help shape the
evolution of these APIs. There is a discussion forum where you can ask
questions, and provide feedback on things you'd like to see added or
changed. We'll then take this feedback and use it to help generate
future CTPs.  The goal in this first CTP was to provide some additional
structure on top of what was already provided by System.IO.Packaging
in .Net 3.0. Now instead of just generic parts and relationships, you
actually have each part from the Open XML spec available as a strongly
typed part. The API also provides package level validation so you'll
know your creating all the necessary content type declarations and
relationship type references."  Online overview: "The 2007 Microsoft
Office system introduces a new file format that is based on XML called
Open XML Formats. Microsoft Office Word 2007, Microsoft Office Excel
2007, and Microsoft Office PowerPoint 2007 all use these formats as
the default file format. Open XML formats are useful for developers
because they are an open standard and are based on well-known
technologies: ZIP and XML. Microsoft provides a library for accessing
these files as part of the WinFX technologies in the
System.IO.Packaging namespace. This SDK is built on top of the
System.IO.Packaging API and provides strongly typed part classes to
manipulate Open XML documents."
