The lastest working draft [WD] has
[[
The namespace for XPath functions that are directly available by name
is  http://www.w3.org/2004/07/xpath-functions. The associated
namespace prefix used in this document is fn:. XPath operators are
named with the prefix op:, XML Schema datatypes with the prefix xsd:,
and types of RDF Schema terms with the prefix rdfs:.
]]

I had adopted XPath's op: editorial style of indicating operators but
that appears to create too much confusion. I use a new editorial style
now, and there is no URL that identifies the operators.

Plesae respond indicating whether this is satisfactory to you. You may
prefix the Subject: with [CLOSED] if you wish to close this issue.
