r - run (§3:2.4.2). The description of a run is confused about whether it is limited to text-only, and whether it contains additional markup. "[A run] Can contain multiple types of run content, primarily text ranges. … A run is a contiguous piece of text with identical properties; a run contains no additional text markup." Part 3 and Part 4 reiterate "…the run, which defines a region of text…" [Implied "text-only" is wrong] Part 3 and Part 4 define with many examples that the run can contain a range of additional text markup in child elements like delText, endnoteRef, fldChar, … (e.g., see §4:2.3.2.23). Part 3 and Part 4 also define that the run can contain non-text items like drawing (DrawingML Object), object (Inline Embedded Object), pict (VML Object), … (e.g., see §4:2.3.2.23).
Proposed change: Clearly define the general concept of a run that can contain multiple types of content, primarily a text range with the same properties. [If the primary intent of a run is for text rather than other content types - if not the primary intent, use words like "such as a text range ...".] This also needs changes to the sections in Parts 3 and 4, including section titles that imply runs are only for text. [The text content is defined by a sub-element, t. §4:2.3.3.30]

Proposed Disposition of DIS 29500 Comment GB-0007 (Modified: 2007-10-27) The document “Office Open XML Overview” was intended to provide some background and contextual information about OOXML for reviewers during both the Ecma adoption stage and the 5-month Ballot stage of the Fast-Track process.

This comment appears to consist of the single letter “r”, which presumably is incorrect.
yes, the dash after the r screwed things up. I have 38 places to fix it . . .
That was quick work! I will not bother to look for any more of these.
should be all done now, at least those caused by em dashes.
