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?]
