the column Anläggning contains over 1000 unique archaeological feature types, all in Swedish. This in contrast to the more than 600 archaeological feature types already in SEAD in English.
there is also a column Fornlämningstyp
which contains 294 different terms describing the type of find. Some of these are certainly duplicates with minor spelling differences (Skärvstanshög vs Skärvstenshög) or (Område med skogabrukslämningar vs Område med skogsbrukslämningar vs Område med skogsbrukslämnngar vs Område med skogsbrykslämningar), while others are incorrectly entered data (RT90 651130.246, 1547667.704) or (L2013:292) or (L2022:5614)
I believe that both of these will fall under the heading “features”
