Please fill in this template when reporting a bug, unless you know what you
are doing.
Description of Problem:
When using /docs:
XML Documentation of indexers inside of interfaces is not permitted.
For a public interface, documentation is required for the indexer,
but putting it there gives a false CS1587 warning.
Exists in gmcs and mcs (version 1.2.4.0)

Steps to reproduce the problem:
1. use gmcs -doc:foo.xml xmlerror.cs

Actual Results:
xmlerror.cs(25,9): warning CS1587: XML comment is not placed on a valid
language element

Expected Results:
Successful compilation, xml documentation should be generated.


How often does this happen? 
Always


Additional Information:
I do not know how the microsoft compiler handles this.

Contents of xmlerror.cs:
Additional code is here to show that similar things do not cause problems.

<code>
///<summary>summary</summary>
public class blah
{
	///<summary>summary</summary>
	public static int Main(string[] args)
	{
		return 0;
	}
}

///<summary>summary</summary>
public interface Interface
{
	//Having the following summary will give warning CS1587.
	//Expected: Adds happily to XML documentation.
	
	//Not having it will give warning CS1591.
	//Expected: Exactly that.
	

	///<summary>Problem!</summary>
	int this[int index]
	{
		get;
	}
}

VS 2005 C# compiler compiles without warnings and generates:
