Re: [tdf-discuss] OOXML ECMA-376, transitionnal and strict


In the sake of documenting this, the UK Cabinet Office decision can be found here:

In this URL there is addditional information about the supoport process:

the main reason behind the ooxml rejection seems to be:

   We considered ODF and OpenXML in view of the UK Government
   definition of open standards, which was set following a full public
   consultation in 2012.

   ODF appeared to meet the definition. However, OpenXML did not appear
   to meet the criteria for market support - particularly regarding
   vendor independence. We found products which appear to implement
   OpenXML but only the most recent products claim to have the strict
   implementation and it is not used as a default format in any
   product. In addition, the development of the standard currently has
   limited involvement from outside a single supplier of office
   productivity suites.

OOXML Transitional is definitely not recognized as a standard, and is
specified in Part 4 of ISO/IEC 29500 exactly because is not a standard
(to make it clear how it differs from the standard). OOXML Transitional
was accepted to ease the transition to the standard, and as such should
have lasted only a few years, while it has been used by Microsoft as the
default OOXML format since forever. In addition, OOXML Transitional is
different for each version of MS Office, and the differences are not
documented (only the first OOXML Transitional was documented).

In addition, OOXML Strict - which is the ONLY accepted standard - is
almost impossible to obtain by normal users, as the process is far from
the usual one, as in order to have an OOXML Strict you must save the
document before performing ANY action (as otherwise the format switches
to OOXML Transitional, which is not a standard).

UK Cabinet Office has clearly documented the reasons why OOXML is not a
standard file format.
