Yes, but where do you define rules like ther must be no whitespace
between the dots in an object path?

That's true. Maybe this is right?

BlockComment = "/*" { UnicodeCharacter | LineBreak } "*/";

In the meantime I change this to:

ObjectPath = [ "." ] ObjectIdentifier { "." ObjectIdentifier }  
( [ "." VariableName ] | [ "." ArrayOffset ] );


Thank you for your hints!
