The current grammar has an argumentList and an argList rule. The argList rule should actually be called parameter list. Here's a possible new grammar rule:

// Parameter Lists 
procedureParameters : LPAREN whiteSpace? parameterList? whiteSpace? RPAREN;
propertyParameters : LPAREN whiteSpace? (parameterList whiteSpace? COMMA whiteSpace?)? valueParam whiteSpace? RPAREN;  
parameterList : parameter (whiteSpace? COMMA whiteSpace? parameter)*;
parameter :
    | optionalParam
    | paramArray
valueParam : positionalParam;
positionalParam : (parameterMechanism whiteSpace)? parameterDeclaration; 
optionalParam : optionalPrefix whiteSpace parameterDeclaration (whiteSpace? defaultValue)?;
paramArray : PARAMARRAY whiteSpace paramArrayName whiteSpace? LPAREN whiteSpace? RPAREN (whiteSpace AS whiteSpace builtInType)?;
paramArrayName : untypedIdentifier;
parameterDeclaration : untypedNameParameterDeclaration | typedNamedParameterDeclaration;
untypedNameParameterDeclaration : untypedNameParameterName (whiteSpace? parameterType)?;
untypedNameParameterName : untypedIdentifier;
typedNamedParameterDeclaration : typedIdentifier (whiteSpace? arrayDesignator)?;
optionalPrefix :
    OPTIONAL (whiteSpace parameterMechanism)?
    | (parameterMechanism whiteSpace)? OPTIONAL
parameterMechanism : BYVAL | BYREF; 
parameterType : (arrayDesignator whiteSpace)? AS whiteSpace expression;
defaultValue : EQ whiteSpace? expression;

Edit: Simplified parameter list so that the codebase has one simple list of parameters to work with.
