Refining the layer a map engine exposes
It's possible that you want to make use of a map engine that contains dozens or even hundreds of layers where you actually only want to expose only a handful of those layers to Weave, for example if you have a WMS map service that's provided by a government department and covers the entire country but you only want to make use of the layers that cover your particular state (assuming the WMS service exposes separate layers for separate states), or if you have a map service that exposes both vector and raster based layers but you're rather split them up in Weave so you have two separate Weave map engine, one that's just vector layers and one that's just raster.
You can do this one of two ways in Weave, depending on it being easier to remove the layers you don't want or if it's easier to include just the layers that you do want. If you want to only list the layers to include in the final map engine you can add a layers tag to the map engine that has one or more individual layer tags within for each layer that you want to include, alternatively if you want to remove layers you'd add a remove tag between the layers and layer tags, e.g.
