How do you delete an attribute in XML?

How do I delete an attribute on an XML node in E4X? I thought this would be easier but I haven't found any examples.

I tried: 

delete xml.attribute("myAttribute");

which gives me the following error: 

TypeError: Error #1119: Delete operator is not supported with operand of type XMLList.

and I've tried: 

xml.attribute("myAttribute") = null;

which causes a compiler error.

In you example just add the [0] in the resulted XMLList, to ensure you delete a single attribute node, it should work:

delete xml.@attributename[0];

Actually, for me delete with XMLList works as well for simple cases (without complex e4x search constructions):

    var x:XML = <x><c a="1"/><c a="2"/></x>;
    trace("0", x.toXMLString());
    delete x.c.@a;
    trace("1", x.toXMLString());

output:

[trace] 0 <x>
[trace]   <c a="1"/>
[trace]   <c a="2"/>
[trace] </x>
[trace] 1 <x>
[trace]   <c/>
[trace]   <c/>
[trace] </x>
