Now, when I compile this, I get the following three errors:

There are no errors in the LegDataObjectClass itself.
I've checked thoroughly for spelling, capitalisation, and semicolons
etc. I really don't get why I would get a syntax error! I've tried
to change the declaration to another class (e.g. NSNumber
*aTempLegDataObject;), and then there's no syntax error found. Could
there be some obscure compound problem? Or maybe I'm just doing
something silly...
You need to let the compiler know about the existence of
LegDataObjectClass before you use it.
In the header file of the class where you declare the
LegDataObjectClass instance variable you would typically forward
declare the class:
@class LegDataObjectClass; // <- This is probably what you're missing
And in the implementation file you need to actually import
LegDataObjectClass:
#import "LegDataObjectClass.h" // <- This is probably what you're
missing
@implementation Foo
// Stuff
@end
Read more about this in the ObjC language PDF, and in any book on C.
