Maybe it is already available somewhere, but we failed to find it.

The precise proposed addition to the text of ISO/IEC 29500-4 is: §10.7, "Additional representation for dates and times (Part 1, Section 18.17.4 )" For a document of a transitional conformance class, each unique instant in SpreadsheetML time shall be stored as an ISO 8601-formatted string or as a serial value. This would override, for files of the "transitional" conformance type, the statements in Section 18.17.4 which allow only the ISO 8601 date format.

An implementation is permitted to provide an implicit conversion from string-constant to number. However, the rules by which such conversions take place are implementation-defined. [Example: An implementation might choose to accept "123"+10 by converting the string "123" to the number 123. Such conversions might be locale-specific in that a string-constant such as "10,56" might be converted to 10.56 in some locales, but not in others, depending on the radix point character. end example]

I would agree with you that ODF is better that OOXML.

If people had understood how patents would be granted when most of today�s ideas were invented and had taken out patents, the industry would be at a complete stand-still today. The solution . . . is patent exchanges . . . and patenting as much as we can. . . . A future start-up with no patents of its own will be forced to pay whatever price the giants choose to impose. That price might be high: Established companies have an interest in excluding future competitors." Fred Warshofsky, The Patent Wars 170-71 (NY: Wiley 1994).

Řekněme, že jsem to špatně pojmenoval, ale je to totéž o čem mluvíte Vy. Pokud se podíváte např. na http://idippedut.dk/post/2008/01/Embrace-and-extend---SVG-revisited.aspx, tak možná o celé situaci pochopíte víc, než z nějakého příspěvku, který jste silně vytrhnul z kontextu.

Can you provide a definition of what an "existing documents" means?

The problem with that, as I understand it, is that the transitional spec is pretty much unimplementable by anybody except MS
