[Geomoose-users] AGS vector and styling

[Dan Little]

This is a spot we really want to revisit. Some of the vector styling
limitations are due to inherited bugs from both the ol-mapbox-style
library and the mapbox-style specification itself. One thing to keep
in mind is that the catalog can refer to multiple layers in a single
checkbox using ";" as the delimiter for the paths in the mapbook.

Cheers,

-Duck
