Its not possible to use attribute type 'url' as alias in relation properties

Its not possible so save an item, because we have an error from compare widgetToValue and valueToWidget...

What do you mean by not possible? What error/exception do you get?

Error at input mask:

Property tags_tag (tags) did not accept the value (The values differ. Encountered type NULL expected array (Found NULL, expected array ( 0 => 'de/home', ))).

perhaps attributes with serialised values should be excluded

Before the problem can be solved, a new interface must be built into the core and the corresponding implementation built into tags.
