In "Namespaces:", immediately preceding < 

The namespace for XPath functions that are directly available by name  
is The associated  
namespace prefix used in this document is fn:. XPath operators are  
named with the prefix op:, XML Schema datatypes with the prefix op:,  
and types of RDF terms with the prefix r:. SPARQL operators are named  
with the prefix sop:.


fn: =

   I have two preliminary observations:

1. "XML Schema datatypes with the prefix op:". Shouldn't this be xs:,  
judging by 11.1, or xsd:, following convention?
2. The only namespace prefixes listed in 1.1 are rdf:, rdfs:, and  
xsd:. AFAICS, this leaves:
   a) fn: defined, but not listed in 1.1
   b) op:, sop:, xs:, and r: without a definition that I can see in  
this document.

   Thoughts? If someone knows the URI for sop:, I'd very much like to  
be corrected, as I'm trying to write that part of twinql :)
