#Demo using Infectious Disease specialty. 
#(1) Conditions usually imposed on the publisher are just assumed.
#(2) The line "?mainsubject wdt:P1995 wd:Q788926" would causes a bound variable clash,
#with the OPTIONAL section, so the variable ?mainsubject1 is used instead.
#(3) The filter line, comparing ?medrsyear ?ynow, is omitted.
#(4) The results are in chronological order.
