Of course. And again, that's a one-to-one mapping to the difference between no 
values (p == NULL) and one value of zero-length. Since both conditions are 
legal in the ASN.1 data, as a programmer you must handle both. (Even though 
it's nonsensical in this context, and the server is clearly broken.)
