Proprietary OOXML Extensions
Boycott Novell has picked up Rob Weir's tests of Excel 2007. It seems that there are some other formats besides OOXML that have been introduced, such as one that includes macros inside of "binary blobs", which is another way of saying it is non-text encoded, and one that is pure binary. This is supposedly to help it deal with legacy binary data better.
Let me see. Didn't Microsoft dream up OOXML as a way to have an XML format that deals with legacy binary formats better? Does something seem fishy to you? The funny thing is, according to Rob Weir, these particular binary blobs are not in the OOXML specification, so there goes any pretense of interoperability.
