'since these attributes are merely listed but not defined, the ability
to practice the benefit of being "fully compatible with the large
existing investments in Microsoft Office documents" .. is consequently
reserved for Microsoft alone
'even though they "shall use the Parts defined by this Standard
whenever possible" there is not sufficient information for an
independent implementation to read this data or display the "DrawingML
content" contained therein'
'That required parts of the proposed standard are undisclosed and
therefore not " described in detail " not only technically prevents
other vendors, but it also legally encumbers any vendor wishing to
implement OOXML'
"These annotations are often a vital part of documents and their
specification is undefined in Ecma 376"
"As these DRM features are undefined in OOXML other vendors cannot
interoperate with DRM documents created by Microsoft Office"
"As mathematical formulas are defined in an undisclosed format, other
vendors cannot correctly process formulas using OOXML"
"As OOXML doesn't define which units it's based upon other vendors
cannot reliably implement OOXML"
"It is hard to have confidence in the CONFIDENCE function .. The
problem is that this problem is under-defined. One must make an
assumption, not stated here, as to the shape of the data distribution.
Is it normally distributed data? Exponentially distributed? Weibull
distribution? The standard does not define the meaning of this
function sufficiently for one to implement it"
"Here OOXML again relies on undisclosed information, and without
further specification other vendors cannot reliably implement Smart
Tags"
"OOXML allows export of HTML targeted for 3 classes of browsers
however these 3 options are at least ten years .. only includes IE3,
IE4 and Netscape3 and Netscape4"

"the specification itself is over six thousand pages in length, and is
available in only two formats, DOCX and PDF, each a proprietary format
controlled by a commercial software vendor (Microsft and Adobe,
respectively.)"
