A convention is a value for a property that is used when no other opinion has been provided.  Sometimes conventions are called "default values", but this can be confusing because no property has a "default value" upon creation (except for collection-like properties, which start empty).  Conventions need to be explicitly set on a property.

When defining conventions for a property, there are largely three approaches:
1. Do not set a convention at all
