I was after something for a definition related to a image class, background, foreground, label, marker, etc.
We've been using things with respect to stacking with Client side ordering for the most part for quite a long while now.
I'm working on a AutoCAD OGC importer (besides just MAP 3D based) and the ordering aspects are time consuming if left up to the users. So any sort of ordering would have helped. It looks like the ordering is based on how the service advertises it's layers from what I've been able to find.

IMHO layer Z-order is defined by clients who use the maps. Think about
it: when using PosGIS, Oracle Spatial or any other geoinfor resource,
the Z order is undefined by the resource server, it is up to resource
clients to display them to any Z order the define.
