OOXML from the open source perspective

So then Microsoft decided they were going to do an open standard too, and guess what: it is a .zip file and it's got XML streams inside it. But, having said that, it has been difficult in the past to do binary file format interoperability. You can make many good arguments that it is not a benefit to have one company totally dominating the market. You need some sort of file format interoperability.

and

Isn't one file format (such as ODF) better than two? Surely the weakness of having many is the confusion it creates?
Well, yes, and it should be ODF. In an ideal world... yes, a single file format that was a superset of features and so on would be ideal, but it is very difficult to even conceive of that happening. There is just such a lot of vested business interest in this sphere. It is just very difficult to do anything technical. I just can't see anything like that happening.
