<p class="MsoNormal"><span style="color:#1F497D">Good comment. What I think I was getting at was that consumers that don’t understand the extension can safely ignore it. The ext definition in SpreadsheetML requires preserving unknown extensions (18.2.7),
the ones in PresentationML (19.2.1.11) and DrawingML (20.1.2.2.14, 21.2.2.62) don’t.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Perhaps the best thing for Part 3 is to omit that last sentence. That paragraph is intended to give a rough informative overview of the features in MCE, so saying anything about how they work (as opposed to
generally what they do) is probably not a good idea.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="color:#1F497D">“Application-defined extension elements specify a method for defining extensibility points within the markup specification. This allows markup producers to introduce new features scoped to particular
elements within the markup specification. Markup Consumers can disregard these self-contained blocks of additional features.”<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB" style="color:#1F497D">I think that the first two sentences are OK, but the final sentence looks wrong to me. Markup Consumers MAY be able to disregard these extension elements, but only if the markup specification permits
a Consumer to disregard them. The way that ext is specified in Part 1 means that it must be preserved if not understood, so they may never be disregarded. See Part 1 §18.2.7.<o:p></o:p></span></p>

<p class="MsoNormal">A few days ago, I posted to this email list, WG N 0264, “29500-3 (MCE) Revision, WD0.91”. It contains proposed changes by John H. based on an action item he took at the Bellevue F2F meeting.
<a name="_Toc359511609"></a><a name="_Ref191141146"></a>This action item was: Rework this so we don’t appear to be introducing any new terms. Use plain English.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please post your feedback to this list. If we get enough support, we’ll close this issue on the next teleconference; otherwise, we’ll deal with it at the Delft F2F meeting.<o:p></o:p></p>
