With the fix of bug 947 (and bug 862), it is no longer required to explicitly
provide a projection for every layer in a WMS mapfile (this is specific to WMS).
Layers with no projection are assumed to be in the same projection as the
top-level MAP projection and will automatically receive a copy of the map's
original projection if a new SRS is specified in a GetMap request.
The following paragraph from the WMS Server HOWTO should be edited to reflect that:
"However, if your server wants to advertise multiple projections, then at least
a PROJECTION object is required in every layer, otherwise the layers won't be
reprojected. This is just the way on-the-fly reprojection works in MapServer."
I think the new text should say that it is recommended to provide projections
for all layers to avoid possible errors, but that if none is provided then the
top-level map projecion will be assumed.
