Added WMSDescribeLayer format. Thanks bartvde and sbenthall for the patch. I made some minor modifications:

* changed file structure to match other formats (i.e. put version 1.1 parser in a WMSDescribeLayer subfolder) * fixed a type in the example which showed owsURL instead of owsType r=me (closes #1201) git-svn-id: http://svn.openlayers.org/trunk/openlayers@9146 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf
