DOUG MAHUGH, program manager for ISO 29500-based products, Microsoft: One thing to be very clear about here is this: When we say, "support for ODF in [Office] SP2," we intend to write very compliant ODF documents when you save a document. However, it's not a given that everything you can do in the Office UI is savable under ODF. As you're alluding to, there are things -- SmartArt, conditional formatting, things like that -- that we have in Office and that are popular features, where there is no way to save those in ODF, currently.The way we're approaching that, I can share a little bit with you: We're not throttling the UI, as you describe, where certain things are disabled. Rather, at the time you save, we're telling you, "Hey, you're saving in this other format; some information in this document may be lost." That sort of thing. And let me tell you why we made the decision to do it in that particular way: There are situations where some of that functionality may be very useful to the user, even though it can't be serialized out to the format that they're saving in.
