I've also opened up Word and briefly looked at it's XML features, including creating a document based on an XML schema. This didn't seem quite as intuitive, but I need to spend more time with it. My inclination is that Word is not yet ready to be used as an XML editor. For now, we'll stick with XMetaL and XML Spy.
Finally, I opened up FrontPage. I won't go into any of the details of FrontPage other than to say that one of the prebuilt web solutions that it ships with is a weblog solution. Since I have been building a weblog app, I find this interesting. So now I am off to setup the Frontpage weblog solution. More to follow.
