I have defined a field
{{{field|state|default=new|input type=radiobutton}}}
pointing to the attribute state:
Dies ist ein Attribut des Datentyps [[Datentyp::Text]].
Die möglichen Werte für dieses Attribut sind:
* [[Erlaubt Wert::new]]
* [[Erlaubt Wert::accepted]]
* [[Erlaubt Wert::rejected]]
* [[Erlaubt Wert::postponed]]
How is it possible to change the field definition to a combobox where additional values can be added?
According to:

http://www.mediawiki.org/wiki/Extension:Semantic_Forms/Defining_forms
Values dependent on lets you specify a semantic query to refine which allowed values to use.
