I understand that we could label anything that does not fit into any
established type definition as "xs:string", however I doubt this is
correct.

One reason is that any string is equivalent to a sequence of integers:

   xs:integer*

which is quite typed, isn't it?


Probably, we should not speak about "anti-type", but about the "most
primitive" datatype (in the sense that any other can be
derived/expressed from it).


And the most primitive datatype in any type system clearly is:

       xs:integer.
