for projections, more geometry types, schema, and need to decide what to do with features which are crossing tile boundaries and other complicated things like how to download only tiles which are changed since last access. A common OSGeo specification could
be nice to have at that stage, I do not believe that such things bother MapBox so much.<o:p></o:p></span></p>

That's definitely something we should be looking into I'd say.<br>
