I'm confused. When you say a proprietary data format, I presume you
mean Microsoft's closed and undocumented PPT format, as opposed to
PPTX which is ISO/IEC Standard 29500. So you're arguing that
everyone should move to the standard PPTX.
Or did you mean something else?
You seem to assume that OOXML is a fully defined open standard whereby
anybody can take the ISO/IEC document and implement a fully interoperable
product. From what I know about the technical objections that were raised
and ignored in the ISO/IEC equivalent of Last Call, that may not be the
case. (I don't claim technical expertise in this area, however.)
The same objection wouldn't apply, for example, to PDF/A.
