I think, as a practical matter, the defects that occur when one uses an ODF
implementation that is not the one used for the authoring are far more
disturbing than the blemishes you remark about concerning disparities in
PDFs derived from the as-authored ODF documents. There is a problem with
the current state of interoperability for ODF consumers in comparison with
the ubiquity and stability of PDF at this point.
The proofing-errors problems seem to apply to any renditions of the
document, although I agree it is difficult to catch those kinds of problems
when introduced in the ODF to PDF transformation and they are not stand-out
howlers.
Signing the (authoritative) ODF version would be helpful, although we don't
know how many consumers would verify the signature, especially since it is
only being introduced with ODF 1.2 (although implemented in OO.o 2.x and
later). Unfortunately, passing signature verification does not help us deal
with the consumer then presenting that document incorrectly, although it is
some safeguard against documents that have been inadvertently altered. It
would be great not to get defect reports against any of those (altered or
misrendered) as reported blemishes and defects of the specification.
Note that our published errata are all against the PDF versions of the
documents because of the PDF stability advantage in this regard. It appears
that ISO only provides PDF versions (and expects PDF submissions). So the
risk of un-noticed defects is abated, somewhat, by the many eyes that will
eventually find them when making serious use of the material, attempting to
make translations, etc., especially if they are material defects.
Robin, thanks for raising your concerns. It is important that we look at
the relative risks of all options. (I have no idea what the conclusion will
be, though apparently HTML is not on the table [;<).

The technical committee is at liberty to select an authoritative format,
so the following comment (not official advice or direction from OASIS) is
but
mere informal FYI -- personal comment for consideration.
I always recommend that the editable format be considered authoritative.
Here are two of the most important reasons:
1. The OASIS rule about designating an authoritative format (from among the
three
required formats (editable source, PDF, (X)HTML) arose from a concern
that there might be a "difference" between formats, owing to document
conversion/translation operations. That is: conversions are sometimes
(often) imperfect. The notion was: if there *is* a difference, we would
want
a single point of appeal. From this POV, it makes sense to designate
the
authoring format as authoritative, as it evidently represents the
authoring/editorial intent. What are the chances that the authoring
format is "incorrect" from the standpoint of authorial intent, and that
some derived format (the result of conversion) "correct"? Near zero.
If there is a difference, it's because the conversion created the
difference,
and one not representing authorial intent.
The differences we *have* observed resulting from PDF generation and
other
conversion processes are usually small (or very small) insignificant
changes that the human eye does not catch, because proof-readers see
what they know must be written, not what is actually written. That's
why catching typos and similar mistakes is only asymptotic: several
people acting as proof-readers will all miss the same mistake. Now:
why would one want a PDF (which has the typo/mistake NOT representing
the author's intent to be authoritative? It's a process that
guarantees adoption of inadvertent errors -- in known classes of cases.
Better to designate the source (the original) and not the derived
format "authoritative".
2. OASIS allows the creation of derivative works for a range of uses,
"without restriction of any kind."
Official text: This document and translations of it may be copied and
furnished to others, and derivative works that comment
on or otherwise explain it or assist in its implementation
may be prepared, copied, published, and distributed, in
whole or in part, without restriction of any kind.
Now, suppose someone does want to create an annotated (commentary)
version, or other help system that uses the specification text
in an online context. We would want the creator of that derivative work
to *start with* the authoritative format, not with some
non-authoritative
format. If PDF is selected as authoritative, the creator of the
derivative work would need to convert the PDF -- by some means, and all
are
known to pose serious conversion risks, and often generate artifact
differences.
(Ever try to convert PDF into editable format for such a purose?)
That's enough. I'm quite sure Dennis has his own counter-arguments. In
this context, the above text does not count, except as argument for the
TC's consideration. Your game, your choice.
