paragraph numbering & in[..] with paragraph resolution -> semantic refering

[Henning Haeske <haeske@uni-paderborn.de>]

Hi,

as I am still new to context I really have no idea how to realize following:

After each paragraph I like to have at the right bottom corner a small number. 
This number shout increase with every paragraph. The counting should restart 
after every heading (doesn't care which level).

How can I realize this?

Additionaly I like to use this number with the in-command: Instead of 
referering only to the heading number (e.g. 2.3.1) I want to refer to the 
paragraph (e.g. 2.3.1 / 16). But it should also be possible to refer to a 
group of paragraphs (e.g. 2.3.1 / 16 - 18 or 2.3.1 / 16, 21). Maybe with the 
possibility to exchange the / with anything else (e.g. 2.3.1 Abs. 17).

I am really happy for any hint, tip, implementing strategy to realize this. Of 
course: if I have finally a working solution i will enter it into the 
context-wiki.

Thanks, H.
