There are many other warts in the Microsoft covenant not to sue. E.g., the covenant applies only to Ecma Office Open XML; it does not apply to any future version, including a version that might be approved by ISO or a variant that might be actually implemented by Microsoft in MS Office. So Microsoft makes no guarantee that it will not move the goal posts at any time.

IMHO, it all comes down to one question: > *... Is ODF able to handle everything EOOXML was designed for? Is there something you can do in EOOXML that can't be done with ODF? > Microsoft insists that the reason they developed EOOXML is that ODF is inadequate and unable to handle the advanced features of MSOffice, and, most importantly, the billions of binary legacy documents produced by the many versions of MSOffice still in production. > The answer to this question is that ODF can handle everything MSOffice can throw at it. > There are two ways of proving this. >

# re: Office Open XML final draft!!! @ Wednesday, October 11, 2006 1:46 PM The past incarnations of DrawingML have been chaotic. It would be interesting, out of curiosity, to get an accurate history of what changed over time, perhaps to better understand what is supported in what. Here is my take, I am pretty sure I got at least 50% of it wrong :-) - pre-Windows 95 era, Word, Excel and Powerpoint use their own vector drawing layer used to draw shapes, pictures, diagrams, art and charts. Powerpoint, acquired by Microsoft in 1987, has by far the advanced drawing layer (bi-linear gradients, opacity, ...), codenamed Escher (in reference of the famous mathematician). - In Office 95, it is decided to reuse the Powerpoint vector graphics layer in Word and Excel. Migration begins. - Migration ends with Office 97 where both Word, Excel and Powerpoint use the same vector graphics layer, publicly known as MSO (mso97.dll) - In Office 2000, it's all craze about internet and Word tries to export WYSIWYG html. For that end, mark up extensions must be added to account for the MSO drawing layer. Hence the VML (Vector Markup language). Excel and Powerpoint don't support it. Internet Explorer natively supports VML (Internet Explorer's Direct animation vector drawing layer dismissed for performance reasons). - In Office XP, VML migration ends and both Word, Excel and Powerpoint support VML whenever a document is saved as a "Single web page archive" (.mhtml extension). - In Office 2003, nothing changes. - In Office 12, MSO gets rewritten with backwards compatibility in mind. The vector drawing layer uses more sophisticated drawing functionalities which makes it easier to draw themed, 3D realistic  objects. Technically, the differences are akin to the differences between GDI and GDI+. This new shared library is known as E2O and the corresponding mark up language is known as Drawing ML (Ecma TC45 specs). - In Office 14, ??? perhaps the drawing layer is rewritten, again, to 1) use WPF 2) to allow plugins, hence enabling much more sophisticated do-it-yourself scenarios. Use cases : custom charts ; BI analysis tools. Stephane Rodriguez

# re: Specifying the document settings @ Thursday, January 11, 2007 5:11 AM Brian, the fact that you are encouraging people not to use those compatibility flags does not matter at all here. There obviously will be documents with those flags turned on, right? Otherwise you wouldn't have put this in the standard. So it's just a corner case, but still: This means ONLY your office suite will be able to display those documents correctly, even if a competing program implemented the whole specification. Why? Because you didn't specify how those flags affect the display of the document (a hell of a specification you have there...). I still haven't seen any answer to this valid criticism. It's a competitive advantage for Microsoft since the standard is incomplete and your company is the only one that has the missing parts. - Stephan Stephan Jaensch
