Obl:mod and mod
In "SUD or Surface-Syntactic Universal Dependencies An annotation scheme near-isomorphic to UD" (Gerdes et al 2018), it is mentioned that obl:mod relations are put under the mod relation. However I can find 30 obl:mod relations in Sequoia-SUD and 20 in French-Spoken-SUD It seems that they specifically correspond to obl:mod attached to "cop+noun" structures
