/**
* CDetailView displays the detail of a single data model.
*
* CDetailView is best used for displaying a model in a regular format (e.g. each model attribute
* is displayed as a row in a table.) The model can be either an instance of {@link CModel}
* or an associative array.
*
* CDetailView uses the {@link attributes} property to determines which model attributes
* should be displayed and how they should be formatted.
*
* A typical usage of CDetailView is as follows:
* <pre>
* $this->widget('zii.widgets.CDetailView', array(
* 'data'=>$model,
* 'attributes'=>array(
* 'title', // title attribute (in plain text)
* 'owner.name', // an attribute of the related object "owner"
* 'description:html', // description attribute in HTML
* array( // related city displayed as a link
* 'label'=>'City',
* 'type'=>'raw',
* 'value'=>CHtml::link(CHtml::encode($model->city->name),
* array('city/view','id'=>$model->city->id)),
* ),
* ),
* ));
* </pre>
*
* @property CFormatter $formatter The formatter instance. Defaults to the 'format' application component.

*/
public $data;
/**
* @var array a list of attributes to be displayed in the detail view. Each array element
* represents the specification for displaying one particular attribute.
*
* An attribute can be specified as a string in the format of "Name:Type:Label".
* Both "Type" and "Label" are optional.
*
* "Name" refers to the attribute name. It can be either a property (e.g. "title") or a sub-property (e.g. "owner.username").
*
* "Label" represents the label for the attribute display. If it is not given, "Name" will be used to generate the appropriate label.
*
* "Type" represents the type of the attribute. It determines how the attribute value should be formatted and displayed.
* It is defaulted to be 'text'.
* "Type" should be recognizable by the {@link formatter}. In particular, if "Type" is "xyz", then the "formatXyz" method
* of {@link formatter} will be invoked to format the attribute value for display. By default when {@link CFormatter} is used,
* these "Type" values are valid: raw, text, ntext, html, date, time, datetime, boolean, number, email, image, url.
* For more details about these types, please refer to {@link CFormatter}.
*
* An attribute can also be specified in terms of an array with the following elements:
* <ul>
* <li>label: the label associated with the attribute. If this is not specified, the following "name" element
* will be used to generate an appropriate label.</li>
* <li>name: the name of the attribute. This can be either a property or a sub-property of the model.
* If the below "value" element is specified, this will be ignored.</li>
* <li>value: the value to be displayed. If this is not specified, the above "name" element will be used
* to retrieve the corresponding attribute value for display. Note that this value will be formatted according
* to the "type" option as described below. This can also be an anonymous function whose return value will be
* used as a value. The signature of the function should be <code>function($data)</code> where data refers to
* the {@link data} property of the detail view widget.</li>
* <li>type: the type of the attribute that determines how the attribute value would be formatted.
* Please see above for possible values.
* <li>cssClass: the CSS class to be used for this item. This option is available since version 1.1.3.</li>
* <li>template: the template used to render the attribute. If this is not specified, {@link itemTemplate}
* will be used instead. For more details on how to set this option, please refer to {@link itemTemplate}.
* This option is available since version 1.1.1.</li>
* <li>visible: whether the attribute is visible. If set to <code>false</code>, the table row for the attribute will not be rendered.
* This option is available since version 1.1.5.</li>
* </ul>
