          **nodeIn**: asserts that an RDF node n is equal to an RDF term s or is in a set defined by a
          :py:class:`ShExJ.IriStem`, :py:class:`LiteralStem` or :py:class:`LanguageStem`.
  
          The expression `nodeInBnodeStem(n, s)` is satisfied iff:
           #) `s` is a :py:class:`ShExJ.WildCard` or
           #) `n` is a language-tagged string and fn:starts-with(`n.language`, `s`)
