* The ID of the asset.

* The name of the property.
* @param $default
* A default value to use if the asset property is not set.

* @return string
* Returns the value string. This will be an empty string if the property is
* not set. If you need to check whether or not a property is set, use
* Returns the value string. This will return the default value provided by
* the $default paremeter (which defaults to an empty string) if the property
