How to make this section header in ConTeXt?

How to make this section header in ConTeXt?

[Jeroen Heijmans]

Hi,

I'm new to ConTeXt, but so far most things I wanted to do turned out  
to be quite easy. However, now I'm trying to make a particular  
section heading, but I can't get it right:

|---------------------------------------------|
|  SECTION HEADING            Key 1  Value 1  |
|                             Key 2  Value 2  |
|                             Key 3  Value 3  |
|                             Key 4  Value 4  |
|  Text                       Key 5  Value 5  |
|---------------------------------------------|

Or in text, a box containing a section heading in the left top, some  
additional text in the left bottom, and a table with pairs of values  
on the right side of the box.

Getting a box with a section heading and some text was easy enough,  
but I couldn't get the table where and how I wanted it. I also tried  
to do all of it in a table, but I got errors when trying to put a  
\section in the table. Any suggestion on how to do this will be  
highly appreciated.

thanks,

Jeroen Heijmans

Thanks a lot, this is what I'm looking for - although it's a bit more  
involved than I had expected.

you can do it simpler (quick and dirty) but this demos how to write a 
more general interface
