... > Lemma:"de" + token(Form) // set lemma to "de" + Form
... > Feat:"Featname"+this(Lemma) // set the feature Featnamer to the value of Lemma
... > Feat:"Gender"+this(Misc_Special) // set the feature Gender to the value of the Misc Special
... > Misc:"Keyname"+head(head(Upos)) // set the key "Keyname" of column MISC to the Upos of the head of the head
... > Lemma:substring(this(Form), 1, 3) // set lemma to the substring (1 - 3) of Form
