hi all-

few newb questions:


1) i'm adding a dynamic layer via mapscript/php using this code:

 $oMap = ms_newMapobj("/data/ut_night_mosaics.map");

 $oLayer = ms_newLayerObj ($oMap);

 $oLayer->set('name', 'foo');

 $oLayer->setProcessing ("SCALE_1=0,63");
 $oLayer->setMetaData ("wcs_description"     , "F152003 11 28 mosaic");
 $oLayer->setMetaData ("wcs_name"            , "mosaic");
 $oLayer->setMetaData ("wcs_label"           , "vis_mosaic");
 $oLayer->setMetaData ("ows_srs"             , "EPSG:4326");
 $oLayer->setMetaData ("ows_extent"          , "-180 -75 180 75");
 $oLayer->setMetaData ("wcs_resolution"      , "0.00833333 -0.00833333");
 $oLayer->setMetaData ("wcs_bandcount"       , "1");
 $oLayer->setMetaData ("wcs_formats"         , "GEOTIFF");
 $oLayer->setMetaData ("wcs_nativeformat"    , "8-bit GeoTIF");
 $oLayer->setMetaData ("wcs_rangeset_name"   , "vis_mosaic");
 $oLayer->setMetaData ("wcs_rangeset_label"  , "vis");
 $oLayer->setMetaData ("wcs_rangeset_axes"   , "bands");
 $oLayer->setMetaData ("wcs_bands_name"      , "bands");
 $oLayer->setMetaData ("wcs_bands_semantic"  , 
"http://www.ngdc.noaa.gov/dmsp/";);
 $oLayer->setMetaData ("wcs_bands_refSys"    , "European Petroleum Survey > Group 
(EPSG)");
 $oLayer->setMetaData ("wcs_bands_label"     , "F152003");
 $oLayer->setMetaData ("wcs_bands_values"    , "VIS");
 $oLayer->set('status', MS_OFF);
 $oLayer->set('dump', MS_TRUE);
 $oLayer->set('data', "F1520061123.nt.d.OIS.vis.mos");
 $oLayer->set('dump', MS_LAYER_RASTER);
 $oLayer->setProjection ("init=epsg:4326");

 $oMap->owsdispatch($request);
 $contenttype = ms_iostripstdoutbuffercontenttype();
 header("Content-Type: $contenttype");
 ms_iogetStdoutBufferBytes();
 ms_ioresethandlers();

this works fine: i can make wcs requests for the 'foo' layer.  however, a
DescribeCoverage request does not seem to pick up on the dynamic layer via
owsdispatch.  what else should i look into doing?

sorry for replying to my own post, but does anyone have insight into whether
or not the creation of dynamic layers should result in additional components
from a DescribeCoverage request?  is this a feature or a bug?

regards.
