Yes, but the issue is that you havn't defined 'answer set' anywhere.
Since the issues of duplicate answers are so tricky and subtle, just
using this phrase casually leaves the reader felling a little
insecure. (I *ought* to know what it means, but then this whole
business *ought* to be a lot less complicated than it apparently is
... :-)
Solution is probably to just toss in the relevant definition
somewhere, maybe as an extension of one of the current ones, eg
include it as an extra sentence in the answer sequence definition. (?)
