Hi David,
first of all, I agree that integrating the list style into the graphic
properties is not a very nice solution. However, if the file format
should cover the situation how bullet lists are used within presentation
applications, this seems to be required. Here, a graphic style defines
some kind of template for the bullets to be used within the drawing
objects that gets this style assigned. Putting the bullet list
definitions into a separate <text:list-style> element next to the
graphic style's <style:style> element does not work, because then the
list style would have to appear as style in the user interface.
Referencing automatic styles from user interface style (or common)
styles is not allowed by the format, so the only option seems to be to
include the list style into the graphic style.
However, maybe it is an option to include only the
<text:list-style-level-style-*> elements into the graphic style. This
way, the situation would not appear as a list style contained in a
graphic style, but as a graphic style that contains list level
definition in the same way as a list style.
Some more comments are inline.

The problem is that it can be controlled within a derived graphics style
whether the bullet list defined in graphics style actually is applied or
not. The concepts we have so far allow only to switch on and off the
numbering within paragraphs themselves, but not within styles.

The font size would be included in the <style:text-properties> element
contained in the graphic style's <style:style> element. That is, the
font size would be specified in exactly the same way as it is now
proposed to define bullet list information. The only difference is that
the font size is an attribute, while the list style is an element.

This won't work, because graphic styles usually contain some text
formatting properties in addition to real graphic properties, but these
text formatting properties are no separate style objects.
