Enforcing the requirement for the STYLES parameter in MapServer 5.0 has led to issues with a couple of WMS clients, the main one being that GoogleEarth could no longer connect to MapServer WMS services (others such as JUMP were reported to have the same issue).
A long thread of discussions followed, including the development of RFC-35 as a possible solution, and the submission of a change request at OGC to make STYLES optional in the next revision of the spec since it really doesn't need to be required (as was agreed on the wms-dev list). In the end we figured that the best solution was to withdraw RFC-35 and simply revert this change in 5.0.1 and make the STYLES parameter optional again (as it was in v4.10).
This ticket is to document and track this change.

Comment on an old issue, but the requirement for STYLES ( and indeed LAYERS) on a WMS GetMap request only applies when those parameters are not passed in an SLD_BODY or SLD parameter, otherwise they are optional
