Grid object not in 4.0 map file reference

The Grid object does not appear in the 4.0 map file reference.

OK I'm looking at mapfile.c to find out info about the GRID object and need some
help to document it.  From what I can see (and my limited C knowlege):

- GRID object is part of the LAYER OBJECT
- possible parameters are:

LABELFORMAT [string]
MINARCS [double]
MAXARCS [double]
MININTERVAL [double]
MAXINTERVAL [double]
MINSUBDIVIDE [double]
MAXSUBDIVIDE [double]

From a CVS log, i see that John implemented this object (whom I have CC'd), and
I have a few questions.  I assumed the grid object would be beneath the MAP
object, as it is more of a "global" setting.  Why is it part of the LAYER object?  
Also, am I correct on the parameters above?  What can users enter for
"LABELFORMAT".  If you can give a brief description of the parameters that would
be great.
Maybe an example of a layer containing a grid object would also be helpful.  thanks.

John emailed me info on this..accepting bug.

added GRID object to main 4.1-dev CVS mapfile doc (confused as to what the
branch names are now for the doc CVS...anyone know?).

Questions for John Novak:

- I would think that the most popular labelformat would be degrees only (e.g.
"45", and not "45.00" or "45 00" or "45 00 00")...is this currently possible?

- i tried putting in the labelformat parameters in lowercase and it doesn't like
that..shouldn't a lowercase "ddmmss" be acceptable?

For the mapserver_docs CVS, the main trunk is still the 4.1-dev, it has not been
branched yet for 4.2/4.3. This means that any change in the main trunk at this
point is for version 4.2.  I don't think I'm very clear...does my explanation
make sense?
