UBF format

[Vlad Dumitrescu XX (LN/EAB)]

Hi,

I have a silly question. 

In the UBF-A specification, it is said that
	Structs 
		Structures are written: 
	    { Obj1 Obj2 ... Objn }

In the code, the elements can be separated by commas.

Is the comma optional indeed, or did I miss something? Is the recommended use with or without commas?

best regards,
Vlad
