Databinding error: Only one layout element and one data element are allowed.
<p>I'm getting following error when using databinding and include tag inside:</p>

<pre><code>Error:Execution failed for task ':app:dataBindingProcessLayoutsBetaDebug'.&gt;data binding error msg:Only one layout element and one data element are allowed. [path to file] has 3file:[path to file]****\ data binding error ****
</code></pre>

<p>This is my layout file:
    </p>

<pre><code>[...]

        &lt;LinearLayout
            android:id="@+id/activity_description_content"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:orientation="vertical"&gt;

            &lt;include
                android:id="@+id/activity_description_header_bottom"
                layout="@layout/activity_description_header_bottom" /&gt;

            &lt;include
                android:id="@+id/activity_description_contact_info"
                layout="@layout/activity_description_contact_info" /&gt;

            &lt;include
                android:id="@+id/activity_description_other_info_box"
                layout="@layout/activity_description_other_info_box" /&gt;

            &lt;include
                android:id="@+id/activity_description_bottom_buttons"
                layout="@layout/activity_description_bottom_buttons" /&gt;
        &lt;/LinearLayout&gt;
[...]
&lt;/layout&gt;
</code></pre>

<p>And in each of the included layouts i have something like this:</p>

<pre><code>&lt;layout xmlns:android="http://schemas.android.com/apk/res/android"&gt;
[...]
&lt;/layout&gt;
</code></pre>

<p>From this reply: <a href="https://stackoverflow.com/questions/32947440/android-data-binding-using-include-tag">Android Data Binding using include tag</a> i suppose that my code is correct, why databinder thinks that I use more than single tag in the file?</p>
