 Review comment:
   Hi Carsten, this computes "enabled", "guarded" and "readOnly" even when 
"element.isEnabled()" is false. The original expression 
   `element.isEnabled() && !((element.getStatus() == 
RefactoringElement.GUARDED) || (element.getStatus() == 
RefactoringElement.READ_ONLY))`
   does not, though.
