+ * Keyboard Building helper.
+ *
+ * This class parses Keyboard XML file and eventually build a Keyboard.
+ * The Keyboard XML file looks like:

+ *   &lt;!-- xml/keyboard.xml --&gt;
+ *   &lt;Keyboard keyboard_attributes*&gt;
+ *     &lt;!-- Keyboard Content --&gt;
+ *     &lt;Row row_attributes*&gt;

+ *       &lt;Key key_attributes* /&gt;
+ *       &lt;Spacer horizontalGap="32.0dp" /&gt;
+ *       &lt;include keyboardLayout="@xml/other_keys"&gt;
+ *       ...
+ *     &lt;/Row&gt;
+ *     &lt;include keyboardLayout="@xml/other_rows"&gt;
+ *     ...
+ *   &lt;/Keyboard&gt;
+ * </pre>
+ * The XML file which is included in other file must have &lt;merge&gt; as root element,
+ * such as:
+ * <pre>
+ *   &lt;!-- xml/other_keys.xml --&gt;
+ *   &lt;merge&gt;
+ *     &lt;Key key_attributes* /&gt;

+ * and

+ *   &lt;merge&gt;
+ *     &lt;Row row_attributes*&gt;
+ *       &lt;Key key_attributes* /&gt;
+ *     &lt;/Row&gt;
+ *     ...
+ *   &lt;/merge&gt;
+ * </pre>
+ * You can also use switch-case-default tags to select Rows and Keys.
+ * <pre>
+ *   &lt;switch&gt;
+ *     &lt;case case_attribute*&gt;
+ *       &lt;!-- Any valid tags at switch position --&gt;
+ *     &lt;/case&gt;

+ *       &lt;!-- Any valid tags at switch position --&gt;
+ *     &lt;/default&gt;
+ *   &lt;/switch&gt;
+ * </pre>
+ * You can declare Key style and specify styles within Key tags.
+ * <pre>
+ *     &lt;switch&gt;
+ *       &lt;case mode="email"&gt;
+ *         &lt;key-style styleName="f1-key" parentStyle="modifier-key"

+     * position in the update, and the currently expected position of the cursor according to
+     * LatinIME's internal accounting. If this is not a belated expected update, then it should
+     * mean that the user moved the cursor explicitly.
+     * This is quite robust, but of course it's not perfect. In particular, it will fail in the
+     * case we get an update A, the user types in N characters so as to move the cursor to A+N but
+     * we don't get those, and then the user places the cursor between A and A+N, and we get only
+     * this update and not the ones in-between. This is almost impossible to achieve even trying
+     * very very hard.
+     *
+     * @param oldSelStart The value of the old cursor position in the update.
+     * @param newSelStart The value of the new cursor position in the update.
+     * @return whether this is a belated expected update or not.
