public interface DmcNameClashResolverIF

The DmcClashResolverIF defines an entity that can attempt to resolve a clash between colliding object names in a particular namespace. An example usage of this can be seen in the dark-matter schema (DMS) mechanisms. Naming of definitions takes place in a flat namespace, but, internally, definitions have a fully qualified name based on the schema of which they are a part. Generally, you can use the flat namespace name for a definition, it's just more convenient. If there are clashing definition names across schemas, the schema manager maintains a set of the definitions with matching names. When object reference resolution takes place, a DmcClashResolverIF can be used to determine, based on context, which of the objects that map to the name should be used.
