Subject RE: Office to Become Fully Open XML Compliant (at last)

It is incorrect for Andy to claim that Transitional was not part of ISO/IEC 29500 for OOXML.
 It was there initially and still remains part of the specification.  There has been some
tidying up of the boundaries between strict and transitional, but they have always been provided
for in the 4-part IS 29500 specification.

Jim Thatcher's post from yesterday can be found at 

The approach to migration and expansion of format support starting with Office 2003 is nicely-illustrated
by the diagram in that blog post.  The support in Office 2003 was by a "Compatibility Pack"
upgrade and that worked at the transitional level, the only one that made sense that far back.
 The arrangement to consume Strict OOXML before providing producers of it is also sensible.

The most interesting part for me is the greater parity in terms of ODF support, especially
ODF 1.2 and OpenFormula.  The other facet, not mentioned in Thatcher's piece, is that the
Office Web Apps and Skydrive now support the "New Office" formats although not all features
are exercisable in a browser.  But this makes cross-platform interchange possible wherever
Internet Explorer, Firefox, and Chrome run.

I think this expansion of the interoperable support of ODF will benefit the OpenOffice-lineage
community as well as provide more diversity of supporting applications.

But after the dust settled, Microsoft did not fully implement the standard
that it had fought so vigorously to have become a global standard.
Instead, it implemented what it called "Transitional Open XML," which was
better adapted for use in connection with documents created using older
versions of Office.

According to a blog posted yesterday by Jim Thatcher at the Office Next Web
site, Office 13 will - finally - permit users to open, edit and save
documents in the format that ISO/IEC approved. Thatcher says that Office
13 will also provide similar capabilities for the latest version of ODF,
approved by OASIS in January of this year (ODF 1.2), as well as for PDF.
