That's great that Albers, LCC and others should work with TDS 4.3 WMS.
That means it should work on:
which is at TDS 4.3.15.
So on that server, I can get this WMS request to work using EPSG:4326:
But I can't get anything else to work.
Can you provide a modified version of the above request that works for
Albers (EPSG:9822) or LCC (EPSG:9802)
