I asked Holger Knublauch who responded:

" suspect that's the same as

https://stackoverflow.com/questions/62330878/validate-xsddatetime-with-schacl/62353919#62353919

i.e. a JSON-LD syntax misunderstanding (which then propagated in the TTL
too). In particular,

"sh:dataType": {
      "@type": "@id"
    }

isn't supposed to be camelCase :)"
