I'm not sure I understand correctly. You do have file-, directory-, and 
48 more different block types that you want to parse? In that case I 
probably would use 'ERR' instead of 'E"directory or ... expected"' which 
produces a generic parse error without specific reason. Or you could use 
E"top level directive (e.g. file/directory/...) expected" or E"bad block 
type". I can't tell you what you want your error messages to be ...
