Low and behold I have was able to group drawing objects in .odt files. Like presentations, the <draw:g> element is used.

Here is an abridged snippet from what I am attaching:

<text:p text:style-name="Standard">Hello world. The time is now to come to the aid of the country.</text:p>
  <text:p text:style-name="Standard" />
- <text:p text:style-name="Standard">

- <draw:frame>
- <draw:text-box>
- <text:p text:style-name="Drawing">
- <draw:g>
<draw:rect>
<draw:custom-shape>
  </draw:g>
  Drawing
  <text:sequence text:ref-name="refDrawing0" text:name="Drawing" text:formula="Drawing+1" style:num-format="1">1</text:sequence>
  The Grouped Drawing Caption
  </text:p>
  </draw:text-box>

  </draw:frame>

Well you won't get any disagreement from me there. What can I say - I didn't design it. :-)
They are using a text sequence and not a caption per the spec.

So, we agree that structurally captions are poorly implemented. When I went to apply the caption the caption was stuck
outside the draw group - which annoyed me to no end and in fact then it was not a caption but a text sequence. A semantic
mess. So, we have a couple of options as I see it for captions I will throw out:

- put a role of caption on the text sequence.
- define a caption element to be embedded within a drawing object/group and reference the text sequence. 

thoughts?
