Seems passing a list and ref'ing 2x is fine:

	public void testMultipleRefsToListAttribute() throws Exception {
		String templates =
				"group test;" +newline+
				"f(x) ::= \"<x> <x>\""+newline
				;
		StringTemplateGroup group =
				new StringTemplateGroup(new StringReader(templates));
		StringTemplate e = group.getInstanceOf("f");
		e.setAttribute("x", "Ter");
		e.setAttribute("x", "Tom");
		String expecting = "TerTom TerTom";
		assertEquals(expecting, e.toString());
	}

passes.

It must only be the internal list?
