Namespace definition

Description

A namespace denotes a group of identifiers in a program that is distinguished by a common name (prefix). A fully qualified entity name in Mosel is of the form nspc~ident where nspc is a namespace name and ident an identifier in the namespace. The use of namespaces can help structure data when working with multiple packages.
