* ODTUnknownStyle: class for unknown/not implemented ODT style families.
|

* The goal is to at least read in not supported style faimlies and return
|
||||
* the original content on a call to toString().
|
||||
*
|
||||
* The following has to be taken into account:
|
||||
* - the properties of an ODTUnknownStyle can not be changed.
|
||||
* - so setProperty() and importProperties() will do nothing.
