The graphic provided in the example is almost impossible to read, but appears to be malformed XML.
Make an easy to read example (perhaps lighter background color) and make the example well-formed.

Proposed Disposition of DIS 29500 Comment US-0284 (Modified: 2008-01-02) Agreed; it should be noted that some XML fragments are intentionally incomplete and may not validate. Often the fragments will contain ellipses as placeholders allowing the focus to stay on the XML mark-up relevant to the example. A change will be made to Part 3, ยง8.3.4.1.1, page 456, line 1, where the artwork will be replaced by the following text: <extLst mod="true"> <ext uri="http://schemas.openformats.org/presentationml/someextensionpoint"> <new:foo xmlns:new= "http://schemas.openformats.org/presentationml/2008/presentationml"> … </new:foo> </ext> <ext uri="http://schemas.somevendor.com/presentationml/someextensionpoint"> <somevendor:bar xmlns:somevendor= "http://schemas.somevendor.com/V20/ournamespace"> … </somevendor:bar> </ext> … </extLst> Similar Comments: CA-0012 , CO-0075 , FR-0031 , GB-0124 ,

Multiple Comments:
1) Unable to read example.
2) Example is malformed XML.
(1) is a “Just-fix-it”, but (2) may be serious, if it is not possible to make the example correct.
I am going to tag it as just fix it. I know that there is a better comment somewhere about malformed XML.
