title: Are LiveData objects observable in XML?
body: <p>When I bind <code>ObservableField&lt;&gt;</code> objects to a view in XML, changes to the value via <code>set()</code> are immediately reflected in the view. When I bind <code>LiveData&lt;&gt;</code> objects in XML, however, the initial value is rendered but changes via <code>value=</code> have no effect on the view. They <em>are</em> passed to Kotlin observers.</p>
  
  <p>I assumed <code>LiveData</code> would work like <code>Observable*</code> classes in XML bindings. Is that not the case? If I need to observe a value in both XML and Kotlin, do I really need to create two observables?</p>
