Sure would be great if I could just download a wishlist and then re-upload it
to my collection! Not sure if the latter has comments allowing me to keep track
of whether I have built the set or not, but still. Seems odd that the collection
upload won't recognise the downloaded wishlist XML regardless of how many
fields I remove from it. Just keeps giving me "could not find in catalog"
for all sets, whether xxxx-1 or xxxx.
