-/**
- * Parser for BaseKeyboard.
- *
- * This class parses Keyboard XML file and fill out keys in Keyboard.
- * The Keyboard XML file looks like:
- * <pre>
- *   &gt;!-- xml/keyboard.xml --&lt;
- *   &gt;Keyboard keyboard_attributes*&lt;
- *     &gt;!-- Keyboard Content --&lt;
- *     &gt;Row row_attributes*&lt;
- *       &gt;!-- Row Content --&lt;
- *       &gt;Key key_attributes* /&lt;
- *       &gt;Spacer horizontalGap="0.2in" /&lt;
- *       &gt;include keyboardLayout="@xml/other_keys"&lt;
- *       ...
- *     &gt;/Row&lt;
- *     &gt;include keyboardLayout="@xml/other_rows"&lt;
- *     ...
- *   &gt;/Keyboard&lt;
- * </pre>
- * The XML file which is included in other file must have &gt;merge&lt; as root element, such as:
- * <pre>
- *   &gt;!-- xml/other_keys.xml --&lt;
- *   &gt;merge&lt;
- *     &gt;Key key_attributes* /&lt;
- *     ...
- *   &gt;/merge&lt;
- * </pre>
- * and
- * <pre>
- *   &gt;!-- xml/other_rows.xml --&lt;
- *   &gt;merge&lt;
- *     &gt;Row row_attributes*&lt;
- *       &gt;Key key_attributes* /&lt;
- *     &gt;/Row&lt;
- *     ...
- *   &gt;/merge&lt;
- * </pre>
- * You can also use switch-case-default tags to select Rows and Keys.
- * <pre>
- *   &gt;switch&lt;
- *     &gt;case case_attribute*&lt;
- *       &gt;!-- Any valid tags at switch position --&lt;
- *     &gt;/case&lt;
- *     ...
- *     &gt;default&lt;
- *       &gt;!-- Any valid tags at switch position --&lt;
- *     &gt;/default&lt;
- *   &gt;/switch&lt;
- * </pre>
- * You can declare Key style and specify styles within Key tags.
- * <pre>
- *     &gt;switch&lt;
- *       &gt;case mode="email"&lt;
- *         &gt;key-style styleName="f1-key" parentStyle="modifier-key"
- *           keyLabel=".com"
- *         /&lt;
- *       &gt;/case&lt;
- *       &gt;case mode="url"&lt;
- *         &gt;key-style styleName="f1-key" parentStyle="modifier-key"
- *           keyLabel="http://"
- *         /&lt;
- *       &gt;/case&lt;
- *     &gt;/switch&lt;
- *     ...
- *     &gt;Key keyStyle="shift-key" ... /&lt;
- * </pre>
