Hi Thanks for your fast reply.
If I have understood you correctly, it is safe to assume a checkbox is selected, if the value is a value from the available Values but not "Off". But to be honest I don't know what is meant by "The appearance for the off state is optional". Does this mean it's possible to have checkboxes that can only ever be selected?

See ISO-32000-1 section 12.7.4.2.3 "Check Boxes": The appearance for the off state is optional but, if present, shall be stored in the appearance dictionary under the name Off. Yes should be used as the name for the on state. People who are used to reading ISO specifications know that "shall" means that a normative rule is imposed: no other name, except "Off" is allowed for the off state. People who are used to reading ISO specifications also know that "should" means that a recommendation is being made: it is recommended to use "Yes" for the on state, but if you use any other name, your PDF is still valid. (And it is common practice to use names other than "Yes".)
