In the next few weeks, Microsoft will release similar notes for its implementation of the pre-cursor to the ISO for Open XML.

With the release of documentation Tuesday describing the company's implementation of the Open Document Format in Office 2007 Service Pack 2, Microsoft (NSDQ: MSFT) continues to deliver tangible results of a set of interoperability principles it announced in February 2008.

Microsoft unveiled a Web site that goes into great detail about how Microsoft will implement ODF in Office, describing things like how Word does text formatting, how it determines and sets margins in ODF documents, or what font weight gradations describe bold and normal text. Though Microsoft doesn't have default ODF support in Office 2007, it will add support in Office 2007 SP2 (service pack 2).
