- * {@link Ext.Component#id id} (see {@link #get}, or the convenience method {@link Ext#getCmp Ext.getCmp}).</p>
- * <p>This object also provides a registry of available Component <i>classes</i>
- * indexed by a mnemonic code known as the Component's {@link Ext.Component#xtype xtype}.
- * The <code>{@link Ext.Component#xtype xtype}</code> provides a way to avoid instantiating child Components
- * when creating a full, nested config object for a complete Ext page.</p>
- * <p>A child Component may be specified simply as a <i>config object</i>
- * as long as the correct <code>{@link Ext.Component#xtype xtype}</code> is specified so that if and when the Component
- * needs rendering, the correct type can be looked up for lazy instantiation.</p>
- * <p>For a list of all available <code>{@link Ext.Component#xtype xtypes}</code>, see {@link Ext.Component}.</p>
