Projection Problem

Hi,

I noticed that WMS maps with EPSG:4326 coordinates can be re-projected to the default map projection (EPSG:3857). Can I also use EPSG:4326 coordinates in a custom online map, or am I limited to only the Mercator projections specified by the "type" tag?Any other projection(like lcc、albers、stereographic、bonne) supporting re-projection(exception 4326).As I know,AlpineQuest support all above projection(layer re-projection),and I can freely define or modify projection parameters, including the origin, standard latitudes, central meridian, and so on.

And about the new feature "invert axis orientation" of wms1.3,can it be supported?
