Delete Entity in Ms Dynamics CRM 2011/2013 using OData endpoint

This is really part of the brain dump series but haven't really had the time until now.

So to delete an account it would be invoked like this

deleteEntity("AccountSet","ef02108a-0098-e311-81c2-d89d6763fc38'")

var deleteEntity = function(EntitySet, Id)
{
 url = Xrm.Page.context.getClientUrl() + "/XRMServices/2011/OrganizationData.svc/";
 url += EntitySet + "(guid'" + Id + "')"

 delete(url).fail(function(){alert("An error ocurred deleting " + Id)})

}

var delete = function(url)
{
 return $.ajax({
 type:"DELETE", 
 url:url,
 beforeSend:function(x){x.setRequestHeader("Accept","application/json")},
 });
}

Also, jquery needs to be loaded if you are using Dynamics CRM 2011
