An alternative could be to change A.4.3. towards two Index functions
instead of one:

function Index (Source : in String; 
Pattern : in String; 
Going : in Direction := Forward; 
Mapping : in Maps.Character_Mapping) 
return Natural; 
 
function Index (Source : in String; 
Pattern : in String; 
Going : in Direction := Forward)
return Natural;
