well I now agree, but I got it from prehistory and
from http://www-nrc.nokia.com/sw/rdf-datatyping.html
5. RDF Schema for Datatyping
[[[
   <rdfs:Class rdf:about="&rdfs;Datatype">
      <rdfs:label xml:lang="en">RDF Datatype</rdfs:label>
      <rdfs:comment xml:lang="en">
         An RDF Datatype consists of a value space, a lexical space,
         and an N:1 mapping from the lexical space to the value space. 
      </rdfs:comment>
      <rdfs:subClassOf rdf:resource="&rdf;Property"/>
   </rdfs:Class>
]]]

but it is understood now as being the case that
  rdfs:Datatype rdfs:subClassOf rdfs:Class .

have a nice weekend

PS I got running code with
   support for typed literals a la <uri>"string"-la
                                   qname"string"-la
                                   _:lab"string"-la
   and I will further focus on some testcases
