<div dir="ltr">Chris,<div><br></div><div><div>Good start! </div><div><br></div><div>First, I think that we should cover foreign OPC parts. Advantages: </div><div>applications unaware of such foreign OPC parts preserve them, as </div><div>long as they are referenced by relationships. Disadvantages: </div><div>(1) unaware applications discard them if they are not referenced by </div><div>relationships. (2) since such foreign parts augument certain points within </div><div>existing parts, we have to specify which point in which part is augmented.</div><div><br></div><div>Second, in Document Interoperability Initiative event in 2009, Microsoft </div><div>explained extensions of OOXML. Each presentation provides </div><div>very useful information. It shows which extension is done by </div><div>using which mechanism. One option is a combination of a foreign OPC part </div><div>and MCE! Moreover, I vaguely remember that old EXCEL rewrites </div><div>application-defined extension elements beyond them, when rows or columns are </div><div>deleted or inserted.</div></div><div><br></div><div>The link to the presentation materials of this event is:</div><div><br></div><div> <a href="https://www.assembla.com/wiki/show/IS29500/MCE_Best_Practices">https://www.assembla.com/wiki/show/IS29500/MCE_Best_Practices</a><br></div><div><br></div><div>Unfortunately, the link to the Excel extension documentation is broken.</div><div>It should cover rewriting app-defined extension elements.</div><div><br></div><div><br></div><div>Third, an Assembla wiki (<a href="https://www.assembla.com/wiki/show/IS29500/MCE_Best_Practices">https://www.assembla.com/wiki/show/IS29500/MCE_Best_Practices</a>)<br></div><div>summarizes discussions in the past. "Extensibiity and ISO/IEC 29500" by Microsoft (WG4 N0223), </div><div>which is now available at the WG4 E-Committee page is also very useful. </div><div><br></div><div>Regards,</div><div>Makoto</div></div><div class="gmail_extra"><br><div class="gmail_quote">2015-06-10 7:05 GMT+09:00 Chris Rae <span dir="ltr"><<a href="mailto:chrisrae@exchange.microsoft.com" target="_blank">chrisrae@exchange.microsoft.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi all - I'm back from paternity leave and have been reminded that I have action items for SC34. This is probably the largest one - attached is my first draft of some informative text regarding MCE best practises. I began with text of Murata-san's and expanded upon it with examples. It's written in a very informative "primer" style which I thought best suited the subject matter.<br>
<br>
We should probably talk about it in more detail in London next week, but I wanted to give everyone a chance to read it before then. Although they wouldn't be included in the standard itself, I've attached a zip file containing the samples included in my document, should anyone wish to experiment with them.<br>
<br>
See most of you next week,<br>
<br>
Chris<br>
