+</span> * @docauthor Jason Johnston <jason@sencha.com>
+ *
+ * Produces a standalone `<label />` element which can be inserted into a form and be associated with a field
+ * in that form using the {@link #forId} property.
+ *
+ * **NOTE:** in most cases it will be more appropriate to use the {@link Ext.form.Labelable#fieldLabel fieldLabel}
+ * and associated config properties ({@link Ext.form.Labelable#labelAlign}, {@link Ext.form.Labelable#labelWidth},
+ * etc.) in field components themselves, as that allows labels to be uniformly sized throughout the form.
+ * Ext.form.Label should only be used when your layout can not be achieved with the standard
+ * {@link Ext.form.Labelable field layout}.
+ *
+ * You will likely be associating the label with a field component that extends {@link Ext.form.field.Base}, so
+ * you should make sure the {@link #forId} is set to the same value as the {@link Ext.form.field.Base#inputId inputId}
+ * of that field.
+ *
+ * The label's text can be set using either the {@link #text} or {@link #html} configuration properties; the
+ * difference between the two is that the former will automatically escape HTML characters when rendering, while
+ * the latter will not.
+ *
+ * # Example
+ *
+ * This example creates a Label after its associated Text field, an arrangement that cannot currently
+ * be achieved using the standard Field layout's labelAlign.
+ *
+ * @example
+ * Ext.create('Ext.form.Panel', {
+ * title: 'Field with Label',
+ * width: 400,
+ * bodyPadding: 10,
+ * renderTo: Ext.getBody(),
+ * layout: {
+ * type: 'hbox',
+ * align: 'middle'
+ * },
+ * items: [{
+ * xtype: 'textfield',
+ * hideLabel: true,
+ * flex: 1
+ * }, {
+ * xtype: 'label',
+ * forId: 'myFieldId',
+ * text: 'My Awesome Field',
+ * margins: '0 0 0 10'
+ * }]
+ * });
