+     * {@inheritDoc}

+     * <p>The {@link ViewStructure} traditionally represents a {@link View}, while for web pages
+     * it represent HTML nodes. Hence, it's necessary to "map" the HTML properties in a way that is
+     * understood by the {@link android.service.autofill.AutofillService} implementations:
+     *
+     * <ol>
+     *   <li>{@link ViewStructure#setClassName(String)} should be use to describe the type of node:
+     *   <ol>
+     *       <li>If the Android SDK provides a similar View, the full-qualified class name of that
+     *           view should be used.
+     *       <li>Otherwise, the class name should be {@code HTML.iframe}.
+     *   </ol>
+     *   <li>The W3C autofill field ({@code autocomplete} tag attribute) maps to
+     *       {@link ViewStructure#setAutofillHint(String[])}.
+     *   <li>The {@code type} attribute of {@code INPUT} tags maps to
+     *       {@link ViewStructure#setInputType(int)}.
+     *   <li>The {@code name} attribute maps to {@link ViewStructure#setIdEntry(String)}.
+     *   <li>The {@code value} attribute maps to {@link ViewStructure#setText(CharSequence)}.
+     *   <li>The {@code placeholder} attribute maps to {@link ViewStructure#setHint(CharSequence)}.
+     *   <li>{@link ViewStructure#setDataIsSensitive(boolean)} whould only be called with
+     *       {@code true} for form fields whose {@code value} attribute was not pre-loaded.
+     * </ol>
+     *
+     * <p>Example1: an HTML form with 2 fields for username and password.
+     *
+     * <pre class="prettyprint">
+     *    <input type="text" name="username" value="mr.sparkle" autocomplete="username" placeholder="Email or username">
+     *    <input type="password" name="password" autocomplete="current-password" placeholder="Password">
+     * </pre>
+     *
+     * <p>Would map to:

+     *     username.setClassName("input");
+     *     username.setInputType("android.widget.EditText");
+     *     username.setAutofillHints("username");
+     *     username.setIdEntry("username");

+     *     username.setText("mr.sparkle");
+     *     username.setDataIsSensitive(true); // Contains real username, which is sensitive
+     *
+     *     ViewStructure password = //structure.newChildForAutofill(...);
+     *     password.setInputType("android.widget.EditText");
+     *     password.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
