Yes, that was the product of excessively sprinkling xsd types where
they weren't needed. I have updated this text to reflect my 
implementation and several others (note the announcement and responses
[ST]). The editor's draft now has a new type called "simple literal",
defined as an RDF plain literal with no language tag. The operators
STR and LANG return simple literals; the operators <, >, <=, >=,
langMATCHES and REGEX have forms that take simple literals as
arguments.

The examples in the spec reflected the actul implementations. They
have not changed. The operator definitions should now be consistent
with the examples (well, they *should* have been consistent before,
but now I think they are).



Andy, does this complete the response to Example Errors? Let me know
if you need anything else.
