Classification:         Language Definition Problem

Summary:                The entity identifier in architecture and configuration
                        declarations should be work.ENTITYNAME, by a strict
                        reading of the LRM.  This is unnecessary, however.

Description of Problem
----------------------
   A strict reading of the LRM indicates that
   the entity identifier in an architecture declaration and configuration 
   declaration must be referred to as WORK.entityName rather than 
   just entityName according to the visibility rules of the language unless 
   there is a "USE WORK.ALL" clause in effect.  This is pretty silly, though, 
   since other language rules say that this entity (and architecture) must 
   be in the working library.  A strict adherence to the LRM does not change 
   the interpretation of any correct construction, it would only have the 
   effect of saying that some constructions that are completely clear and 
   unambiguous should be flagged as an error.  

   Consider the following example:
        entity E is 
          library GLORP;
        end FOO;
        
        use GLORP.P;  -- i.e. is GLORP known here?
        architecture A of entity E is
         ...
        end A;

Proposed Resolution
-------------------
   We propose that the above entity SHOULD be visible, and that the LRM
   be changed to clarify this.
