Different grids, same axes

["McCann, Mike" <mccann@xxxxxxxxx>]

Hello LAS users (and creators),

I have a problem with a mooring data set where all of the
data are on the same time axis and the same x/y axes (actually,
a single lon/lat point).  Some of the data (e.g. adcp and 
microcat string) are along a multi-point depth axis and some
of the data (wind speed, air temp) are on a single "depth" 
point axis.

I would like to reuse the common axes for these data, but 
addXml.pl reads the two different grids and writes duplicate
x, y, & t axis information. e.g.:

 <hourlyM3_nc_LONGITUDE type="x" units="degrees_east">
  <v>237.039993286133
  </v>
 </hourlyM3_nc_LONGITUDE>
 <hourlyM3_nc_LATITUDE type="y" units="degrees_north">
  <v>36.560001373291
  </v>
 </hourlyM3_nc_LATITUDE>
 <hourlyM3_nc_DEPTH type="z" units="m">
  <v>3.5
  </v>
 </hourlyM3_nc_DEPTH>
 <hourlyM3_nc_TIME_HR type="t" units="hour">
  <arange start="1998-03-24 00:00:00" step="1" size="17161"/>
 </hourlyM3_nc_TIME_HR>
 <hourlyM3_nc_LONGITUDE type="x" units="degrees_east">
  <v>237.039993286133
  </v>
 </hourlyM3_nc_LONGITUDE>
 <hourlyM3_nc_LATITUDE type="y" units="degrees_north">
  <v>36.560001373291
  </v>
 </hourlyM3_nc_LATITUDE>
 <hourlyM3_nc_DEPTH_10 type="z" units="METERS">
  <arange start="10" step="10" size="50"/>
 </hourlyM3_nc_DEPTH_10>
 <hourlyM3_nc_TIME_HR type="t" units="hour">
  <arange start="1998-03-24 00:00:00" step="1" size="17161"/>
 </hourlyM3_nc_TIME_HR>


If I remove the duplicate LAT, LON, & TIME tags and everything 
works fine in LAS.

Can addXml.pl be given some smarts to recognize duplicate axes
and not write them out?  Is there some other approach I should 
take?

My data set is at 
http://dods.shore.mbari.org/cgi-bin/nph-nc/data/OASISdata/netcdf/hourlyM3.nc

Thanks in advance for your help.  LAS is a great product.
