Possible UC7 for consideration...

In this example an annotation has been created which spans from the  
text:p of the comment for an image through this paragraph and into the next.

  Perhaps we have missed considering locality in the document. 
  <office:annotation-end 
     office:name="supereffective" 
     delta:insertion-change-idref="ct2" 
     delta:insertion-type="insert-around-content"/>
  
  And this part is more about the water cooler and how we all need to
  get more sun this winter.
