  <div class="markdown level0 remarks"><p>This attribute is used with classes of elements of <a class="xref" href="C1.LiveLinq.Collections.IndexedCollection-1.html">IndexedCollection&lt;T&gt;</a> and other collections implementing <a class="xref" href="C1.LiveLinq.IObservableSource-1.html">IObservableSource&lt;T&gt;</a>.
It gives you a way of changing the value of <a class="xref" href="C1.LiveLinq.IObservableSource-1.IsDeletedStateAvailable.html#C1_LiveLinq_IObservableSource_1_IsDeletedStateAvailable">IsDeletedStateAvailable</a> without
having to create a full-blown custom implementation of the <a class="xref" href="C1.LiveLinq.IObservableSource-1.html">IObservableSource&lt;T&gt;</a> interface.</p>
