#TargetType.TaggedValue	CommaSeparatedExampleValues	Short Description
#Attribute.CheckIdNameConflict	True,False	Avoids warning about naming conflicts between a table and the automatically named ID columns when generating an SQL database.

This is a way to turn off the evolve feature (auto-evolve or the generate database). We usually warn the user that this name will be in conflict with the naming rules of the SQL server. If you are sure as a designer or developer that you want these names used anyway, you can set this to "false" and the evolve feature will use these probably conflicting names in your database.
