I propose the following text to be included in the "Errata in RDF"
document [1] in the section concerned with RDF concepts [2]:


=======================
The following text, in the second bullet of the subheading "The value
space" of Section 5.1 of the RDF Concepts document:

    disjoint from the value space of any XML schema datatype [XML-SCHEMA2]

should be replaced by:

    disjoint from the value space of any other present or future
datatype (e.g., XML schema [XML-SCHEMA2]), with the exception of future
sub- or supertypes of this datatype

The reason for the replacement is that the definition was ambiguous: the
relationship between the value space of rdf:XMLLiteral and the value
spaces of datatypes not defined in the 2001 version of XML Schema (e.g.,
rdf:text) is unclear.  For example, one cannot infer from the
specifications whether there is overlap between the value spaces.

No one who cannot rejoice in the discovery of
his own mistakes deserves to be called a
