By rereading your message (desired output, and Bruce's reply), I think I understand 
your point. You don't want to sort by doc-number. You want to treat the records that 
don't have a title, as if they do have a title, taken from another record with the same
doc-number. Is that correct?

What processor are you using? I mean, would it be OK to do a transformation
in two steps?
