Traditionally, there has been no widely adopted
vendor/system-independent format for specifying style
information. Hopefully now that there is an organization
(the OGC) addressing open standards for geographic data
(including styling: SLD) there will be more support for a
Wouldn't it be great if data suppliers delivered a .sld
(or something like it) with .shp? And Open Source software
like Quantum, gvSig, OpenJump, and Mapserver actual read the
styling and applied it?

Arc* tools, like almost every other GIS tool, have their own

A very good goal. The great thing about default styling is
that it can produce a good looking map. You could then
change the styling if you want to (because without it you
HAVE to; what a productivity killer!).

That would be good too...
