I'd like to pass an Apex class that I've defined as a public inner class to a Visualforce component. When I try to save the component, I get these errors:

Error: Unsupported type SimpleOuter.SimpleInner[] encountered.

Error: Apex class 'simpleouter.simpleinner' does not exist.

Here's my sample code:

public with sharing class SimpleOuter {
public class SimpleInner {
public String one;
public String two;
}
}

<apex:component>
<apex:attribute name="phoneStatuses" type="SimpleOuter.SimpleInner[]" required="true"
description="The phone numbers and statuses to display." />
</apex:component>
