Description

We now support using $.args in XML if=$.args.foo attributes. However, it would be very useful if you could use it as value of any attribute, as well as value in TSS. The following should then result in a Window containing a label that says _bar_: *index.xml*

<Alloy>
	<Window class="container">
		<Require src="foo" foo="bar" />
	</Window>
</Alloy>

*foo.xml*

<Alloy>
	<Label text="$.args.foo" />
</Alloy>

Currently this compiles to:

    $.__views.foo = Ti.UI.createLabel({
        text: "$.args.foo",
        id: "foo"
    });

If you try to use $.args.foo in TSS it will fail to compile with:

[ERROR] Expected "Alloy", "L", "Ti", "Titanium", "WPATH", "[", "false", "null", "true", "undefined", "{", comment, end of line, number, string or whitespace but "$" found.
