[OpenLayers-Dev] OpenLayers and accessibility

[Roald de Wit]

Hi Thijs,

The license incompatibility (GPL v3) may become an issue if code gets 
used from your project. Is there any way you could contribute the 
relevant code to OpenLayers (which is under the 2-Clause BSD license), 
provided that C2C wants to incorporate your code of course?

Thanks, Roald
