[Accessibility-ia2] Relations to move to previous/next paragraphs

Malte, How much of a burden would it be to provide flows from/to relation 
between all the objects.  Today the AT has to go out to the document 
object to make the connection between paragraphs.  Please see Mick's 
comment in item 8 of the minutes for the prior IA2 meeting at 
http://www.linuxfoundation.org/en/Accessibility/IAccessible2/Minutes/20081202

When I suggested the "prev/next" stuff in that CSUN meeting, I was not
sure about the concrete name, but "flows from/to" was exactly what I
meant. I didn't want to define an additional one.

For the implementation:
IIRC, our (OOo Accessibility API) intention was to help AT to follow the
text flow correctly, when ONE paragraph flows to multiple pages,
optionally divided by some header/footer:

<PARAGRAPH-XY - only some part of it on page n>
<optional: page footer>
<optional: page header>
<PARAGRAPH-XY - on page n+1, rest of the SAME paragraph on prev page...>

The intention was to then connect the two paragraphs via flows from/to.

There was no intention to connect all paragraphs this way in reading
oder, and also not to do anything special in the table scenario
described below...

Malte.
