Qualified Identifier
Qualified Identifiers are used in case where there an ambiguity as to which entity an identifier can refer to. In such cases, the identifier is paired with a Qualifier.
An identifier can be "fully qualified" by combining all possible qualifiers. For example, a complete file path.
