More Compound-Document Formats

The set of compound-document file formats seems to be expanding. At one time, the debate was primarily between Apple's Bento and Microsoft's offerings. Then came a set of formats using XML like OOXML:

and ODF:

As if two XML compound-document formats weren't enough, there is now a move to promote a new compound-document format called CDF that is being promoted by the W3C:

And then there's Verdantium, which saves compound documents in a XML format that is closely aligned with Java's XML object serialization. It's going to be interesting to see what happens.
