Hi Bart,
Not lame at all; these servers are out there, and it's (much) better to
handle them than not to.
I think the proposed code is a good to handle the situation, and it
seems to work. I'll finish building out a set of tests, then submit a
pull request.
Thanks much for your help!
Chris

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

Hello,
I am getting the attached response from an ArcGIS WCS server, with
request DescribeCoverage and protocol version 1.1.0. 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.
Specifically, the OpenLayers namespaces object includes this line:
ows: "http://www.opengis.net/ows/1.1";
This in turn is used to generate a namespaceAlias lookup, which will
return "ows" when looking up "http://www.opengis.net/ows/1.1";.
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.
I am unsure how to proceed. I can't tell if I am encountering a
misbehaving server, or if this is just a limitation of the way
OpenLayers is architected (hard-coded namespaces that can only have
one namespace map to a given alias). Or have I misunderstood
something at a more fundamental level?
Thanks for your advice!
Chris
