 Lookup of the name of an imported package or class deviates from the normal lexical lookup.  For example, consider \lstinline!A.B.C! in the clauses \lstinline!import A.B.C;!, \lstinline!import D = A.B.C;!, or \lstinline!import A.B.C.*;!.
 Here, lookup starts with the lexical lookup of the first part of the name (\lstinline!A!) at the top-level.

 \lstinline!Modelica.Math.ComplexNumbers!.  $\mathit{definitionname}$ is the simple name without dot notation of a single definition that is imported.  A $\mathit{shortname}$ is
 a simple name without dot notation that can be used to refer to the package after import instead of the presumably much longer $\mathit{packagename}$.
