<p class=MsoNormal>Greetings,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Over lunch today I spent some time thinking about versioning
based on our earlier conversation today. I found the documents that
Gareth and Alex mentioned very insightful ( thank you ). I know we’ve
all been tasked with going back and doing some deeper thinking about versioning
– which I’ll do – but I wanted to test a best principle of
mine regarding the evolution of the standard. I’ve always been of
the opinion that as the standard evolves, new features should be added in a
backward compatible way ( using a variety of pre-existing technologies such as
OPC, MCE, extLst, etc. ) and that breaking changes would be very rare. Since
any deeper thinking on versioning on my part would be based on this premise, I
wanted to verify if folks in WG4 saw things similarly.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I put DR-08-0012 in the subject line because I could see a
logical argument being made that if we were willing to break the namespace, “anything
goes.” I believe that this would be an extreme mistake for the
standard. And so I wonder if we ought to put text into the response for
DR-08-0012 explaining the extra-ordinary circumstances behind this change and
explicitly call out that this should change not be used as justification for
additional breaking changes.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I look forward to hearing what others think we ought to do
here.<o:p></o:p></p>
