allow document of a given class (irrespective of its source

;; |

;; | If the attribute's value is clip, the text that does not fit
|
||
;; | into the text box is not displayed.
|
||
;; |
|
||
;; | If the attribute value is auto-create-new-frame, a new frame
|
||
;; | will be created on the next page, with the same position and
|
||
;; | dimensions of the original frame.
|
||
;; |
|
||
;; | If the style:overflow-behavior property's value is
|
||
;; | auto-create-new-frame and the text box has a minimum width or
|
||
;; | height specified, then the text box will grow until the page
|
||
;; | bounds are reached before a new frame is created.
|

;; `----
|

|
||
;; Unfortunately, LibreOffice-3.4.6 doesn't honor
