This gives us a little more flexibility. It means that each of the last three qualifiers are flexible - returned if known, blank if not. The use of three distinct OPTIONAL elements means the three are independent of each other; if they are in the same clause then they would only show up if all three exist. NB: start dates and seats are complete back to 1832, parties back to about 1923 - so for older data you may need to make party OPTIONAL. Election data also requires careful handling - while it seems intuitive that all terms begin at an election, in practice some will reflect mid-term party changes and so do not have this value, so again OPTIONAL is useful. If you want to explicitly only look for sitting MPs, you can forbid a variable:
