Description of Problem
----------------------

In the second of two allowed variations of the conformance rules, the
term "selector" is used to describe what is in fact the "suffix" of a
selected name.

Proposed Resolution
-------------------

Please change the word "selector" to "suffix".

VASG-ISAC Analysis & Rationale
------------------------------

The submitter is correct. This oversight is undoubtedly a copy error
from the Ada LRM. Ada has a production:

  selected_component ::= prefix.selector

The corresponding VHDL production is

  selected_name ::= prefix.suffix

VASG-ISAC Recommendation for IEEE Std 1076-2002
-----------------------------------------------

Interpret the LRM as if the recommended change were in effect.

VASG-ISAC Recommendation for Future Revisions
---------------------------------------------

Change the LRM as proposed.
