potential usage for nested widgets/requires

index.xml

<Alloy>
    <Window>
		<Widget src="genericContainer">
			<Label>hi there</Label>
			<Label>another label</Label>
			<Button>and a button</Button>
		</Widget>
	</Window>
</Alloy>

widget.js

var args = arguments[0] || {};

// assuming Alloy now passes a "children" argument to the widget/require
var children = args.children || [];

for (var i = 0; i < children.length; i++) {
    $.container.add(children[i]);
}

widget.xml

<Alloy>
    <Label>some label that won't affect the incoming children</Label>
    <View id="container"/>
</Alloy>
