Questions on enumeration and itemize

[Christophe Pythoud <pythoud@moria.ch>]

Hi,

1)

I have some legal documents to typeset of the form :

1    This is an article
1.1  this is a subarticle detailing some point
1.2  this is a second subarticle

2    This is an other article
2.1  this is a subarticle
2.2  etc.

I do:

\defineenumeration
  [artst]
  [location=left,
   text={},
   width=3em,
   headstyle=normal]
\setupenumerations[artst][headstyle=bold,style=bold]
\setupenumerations[subartst][headstyle=normal,style=normal]

and I get the main items (1 and 2) typeset in bold (which is what I want). 
But the minor items (1.1, 1.2, 2.1, etc.) are not typeset the way I was 
expecting them to be: the text is in normal style (what I want) but the 
number is in bold (I want them as normal text).  I don't understand why 
this happen.  I was under the impression that the second \setupenumerations 
should not even be necessary.  What am I missing?

2)

Later in the same document, I want to have at some point:

2    bla bla
2.1  bla bla
2.2  bla bla :
     a)  bla bla
     b)  bla bla
     c)  etc.

What I do for now is:

\startitemize[a][width=3em,stopper=)]
\item some text ;
\item some more text.
\stopitemize

which gives me:

2.2  bla bla
a)   bla bla
b)   bla bla
c)   etc.

Quite nice but not exactly what I want.  How do I place the whole 
enumeration 3em away from the margin?  BTW, is there a way to do that for 
any paragraph (I mean a random paragraph in some text, not as a global 
setting).  I have been trying every possible combination of commands I 
looked up in the manuals but to no avail.  Any help would be greatly 
appreciated.

I'm using ConTeXt beta from March 27, 2002.

A nice day to all,

Christophe
