Hi all,

ok, my interpretation of the list style is some how OpenOffice.org driven.
I agree that each <text:list> element starts a new list. OpenOffice.org 
uses attribute text:continue-numbering="true" to achieve the 
interpretation, that all lists using the same list style belong together.

I propose that all <text:numbered-paragraph> by default should belong to 
*one* list. Thus, by <text:numbered-paragraph> a list with different 
list styles is possible.

I propose to introduce the attribute text:style-override for the 
<text:list-item> element to support different list styles inside a list 
defined by the <text:list> element.

I propose to introduce the attribute text:list-id for the 
<text:numbered-paragraph> element to define a group of 
<text:numbered-paragraph> element to belong to an own list.

Regards, Oliver.
