----------------------------------------------------------------
There need to be some more changes to check boxes as the current implementation
assumes that the On value is always COSName.Yes. As the spec has a 'should' for
that we can't rely on that. I propose that we
- change getValue/getDefaultValue to return the actual value as string
- allow setValue/setDefaultValue to use an (arbritary) string and throw an
IllegalArgumentException if the value doesn't match the potential values
- adjust check/uncheck/isChecked accordingly
- add getSelectableValues() to return a list of possible options
In another step we need to deal with fields where there is no appearance
defined (which shouldn't be the case for properly defined fields)
WDYT?
