procedure Check_Validity
(Comp : in Record_Component;
Query : in String);
-- Checks if Comp is valid in a sense as defined in 22.1. Raises
-- Asis_Failed and sets the corresponding error status and diagnosis in
-- case if the check fails. The Query parameter is supposed to be the name
-- of the query where the check is performad.
procedure Check_Validity
(Comp : in Array_Component;
Query : in String);
-- Checks if Comp is valid in a sense as defined in 22.3. Raises
-- Asis_Failed and sets the corresponding error status and diagnosis in
-- case if the check fails. The Query parameter is supposed to be the name
-- of the query where the check is performad.
procedure Raise_ASIS_Inappropriate_Component
(Diagnosis : String;
Component_Kind : Component_Kinds);
-- Raises ASIS_Inappropriate_Element with Value_Error Error Status.
-- Diagnosis usially is the name of the query where the exception is
-- raised. Component_Kind, if not equal to Not_A_Component, is used to put
-- in the ASIS diagnosis string some information to distinguish the
-- queries with the same name which are defined for both Record_Component
-- and Array_Component.
