 /**

  * <p>

  * <strong>Put an attribute in enclosing attribute container tag.</strong>

  * </p>

  * <p>

  * Enclosing attribute container tag can be :

  * <ul>

  * <li>&lt;initContainer&gt;</li>

  * <li>&lt;definition&gt;</li>

  * <li>&lt;insertAttribute&gt;</li>

  * <li>&lt;insertDefinition&gt;</li>

  * <li>&lt;putListAttribute&gt;</li>

  * </ul>

  * (or any other tag which implements the <code>PutAttributeTagParent</code>

  * interface. Exception is thrown if no appropriate tag can be found.

  * </p>

  * <p>

  * Put tag can have following atributes :

  * <ul>

  * <li>name : Name of the attribute</li>

  * <li>value : value to put as attribute</li>

  * <li>type : value type. Possible type are : string (value is used as direct

  * string), template (value is used as a page url to insert), definition (value

  * is used as a definition name to insert), object (value is used as it is)</li>

  * <li>role : Role to check when 'insertAttribute' will be called.</li>

  * </ul>

  * </p>

  * <p>

  * Value can also come from tag body. Tag body is taken into account only if

  * value is not set by one of the tag attributes. In this case Attribute type is

  * "string", unless tag body define another type.

  * </p>
