I also think it is important.  The comments that started this thread
wanted this.

Yes, the v2 mechanism is a bit 'low level'.  However, I don't see that
being able to specify the content of the list item label is layout. The
examples incorporate semantics and ordering.  Indicating list grouping
or continuation is providing information about the content and that
should be allowed to control the content of the labels.  Using this
information to indicate that the label format is carried forward from
the previous member of the group and (optionally) continuation of a
numbering sequence seems a legitimate content requirement.  

Further it seems reasonable that we could ask the formatter to use this
information as a hint that the authors would like these lists laid out
in a consistent way where this a resaonable request. In particular,
making the indentation consistent across the component lists in a static
rendering such as one might print out can help to make a more readable
