   * <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>
