Hi Boris,

I have just read your answer [1] to Michael Sperberg-McQueen's comments 
[2] on the public comment mailing list.  Althought, for the most part, I 
agree with your response to the namespace issue,  I think  that, when "fn" 
prefix is used in the context of  XQuery, we should use the exact same URI 
defined in XPath/XQuery functions and operators spec [3]. In an XQuery 
context, function names are identified by QNames, not URIs.  An example 
can be found in section 5.3.1 : 
 declare function  rtfn:text-length($arg as rdf:text?) as xs:integer{
  return fn:string-length(rtfn:string-from-text($arg))

This namespace issue could be addressed by defining two prefixes: fnr with 
a "#" at the end, and fn exactly as it appears in XPath/XQuery functions 
and operators spec, which will only be used in an XQuery context.

Best regards,
