Enhancement Detail:
A context is a design unit that contains library
declarations and package references.  
Referencing a context is equivalent to referencing 
the libraries and packages locally.  

Exactly one context is permitted to be referenced
by a design unit.  
A context clause may reference other context clauses.


A context is referenced by context reference:
Library Lib_P1 ;
context Lib_P1.project1_ctx ;

There exists a context in the work library named 
default_context.  With the perspective of the current
language definition, the default_context contains:
Context default_context is
  library std ;
    use std.standard.all ;
  library work ;
end ;

To promote the use of ieee standard packages, the proposal 
recommends that the default context be the following:

Context default_context is
  library std ;
    use std.standard.all ;
  library work ;
  library ieee ;
    use ieee.std_logic_1164.all;
    use ieee.numeric_std.all ;
    use std.textio.all ;
end;
