The web-pages referred to below provide information about the European Commission’s March 2004 Microsoft Decision, the Court of First Instance proceedings relating to that Decision, and its ongoing implementation.

Antitrust: Commission imposes € 899
million penalty on Microsoft for non-compliance with March 2004 Decision

"Today's announcement is still all about the rest of the world interoperating with Microsoft on Microsoft's own terms, not the other way around," said Thomas Vintje, a lawyer representing the European Committee for Interoperable Systems, a Brussels-based group representing Microsoft competitors like Adobe, Nokia and Oracle, which brought one of the new complaints that led to the current EU commission investigations of the company. "The world needs a permanent change in Microsoft's behavior, not just another announcement," he said.

the WG is busy working on a first draft. This'll include mainly work in Wordprocessing. Spreadsheet and Presentation is
still in the very early work. So help from the ODF TC would be great --- and a liaison would make sense IMHO.

To give you an idea why help from the ÓDF TC would be needed I'll briefly outline some questions which arose:
* Need for more use-cases, i.e. feasable interop scenarios
* Discussions of unspecified behaviour (e.g numbering in 1.0, spreadsheet formulas, compatibilty options, etc.) and
their impact on interop scenarios
* Questions regaring generic settings like e.eg. form:control-implementation="ooo:com.sun.star.form.component.Form", or
tweaking a la http://www.openoffice.org/issues/show_bug.cgi?id=51726.
* Possible interop problems not handled by the specs (e.g. graphics, WMF, EMF, SVM, etc.) or e.g. font metrics and font
embedding.

As you see there are a lot of overlapping areas with eg. the "ODF interop" we dealt with in the workshop in Barcelona.
[This issue is hosted in the Adoption TC, right? Maybe this TC is also suited as a liaison partner?]
