Hmm, I must have misunderstood this aspect. In my mind I was thinking
that if a varlen attribute were at the end, these functions would make
it easier to access them quickly. But from this and the follow-on
responses, these would be used to access varlen attributes wherever
they may be. I'll take a look at the current uses of GETSTRUCT().
