== Overview ==

Correct rendering of road networks requires ordering. Major roads should be rendered
over the top of minor roads.

== Motivation ==

Currently MapGuide Studio exposes the ability to order individual styles within a layer, [[BR]]
however, the server doesn't support ordered rendering. The only work around currently[[BR]]
is to break road networks into separate layers.

== Proposed Solution ==

Add support to the rendering engine to render layer styles in ordered passes.

This should only require changes to the rendering engine, there would be no [[BR]]
xml schema schema changes required


== Implications ==

None.

== Test Plan ==

None.

== Funding/Resources ==
