[OpenLayers-Dev] ESRI // WCS DescribeCoverage 1.1.0

[Bart van den Eijnden]

I know this is lame as a workaround, but you could define another namespace with a different key and then just copy its readers. Untested patch:

OpenLayers (latest 1.x from GitHub) cannot retrieve the Title or Abstract attributes because the namespaces referenced in the OpenLayers.Format.WCSDescribeCoverage.v1_1_0 object conflict with what is referenced in the document.

However, in this case, I need "ows" to be mapped to "http://www.opengis.net/ows".  If I make that change in the namespaces definition, tests break.  Unfortunately, given the way the aliases are defined, I cannot add a second namespace that maps to "ows", which might fix my problem.
