Why I can't combine %TYPE with [] ?

I've checked in the PostgreSQL 7.3.4 sources
(backend/parser/parse_type.c) and especially the char *
TypeNameToString(const TypeName *typename) function.

At the end of this function it seems that manages %TYPE that is combined
with [] :

if (typename->arrayBounds != NIL)
appendStringInfo(&string, "[]");

so I'm asking why I can't write a PL/PGSQL function like

CREATE OR REPLACE FUNCTION myownfunction(members.id%TYPE[],
events.id%TYPE) RETURNS BOOLEAN AS '

Am I looking at the wrong place in the sources ?
