[mapguide-users] Creation mapdefinition using Maestro

[Kenneth Skovhede, GEOGRAF A/S]

Generally, you should use the same coordinate system on your map as your 
data has (best performance).

However, WGS 84 is a world spanning coordinate system 
(latitude/longitude), and
might be a "fallback" because the provider is unable to detect the 
correct coordinate system.
