RE: [F&O] 14.1.3 fn:namespace-uri can no longer return a string

Sarah:
We discussed your comment at the joint WG telcon today.
As Michael Kay pointed out in http://lists.w3.org/Archives/Public/public-qt-comments/2004Sep/0044.html the grammar in RFC 2396 prohibits the zero-length
string but the RFC defines semnatics for it.  So, we took the position that
the zero-length string was, indeed, a valid URI and so it could be returned.
I'll change some of the wording to make this clear.

Please let us know if this is satisfactory. 


All the best, Ashok

Subject: [F&O] 14.1.3 fn:namespace-uri can no longer return a string



In F&O 14.1.3, namespace-uri was changed to return an xs:anyURI instead 
of an xs:string. The sentence "If $arg is the empty sequence, the 
zero-length string is returned" is no longer valid. There may be other 
occurrences of this in the document where xs:string was changed to 
xs:anyURI.

In similar cases (11.2.3) the signature is xs:anyURI?.

So either:
fn:namespace-uri() as xs:anyURI?
fn:namespace-uri($arg as node()?) as xs:anyURI?

If $arg is the empty sequence, the empty sequence returned.

or:
fn:namespace-uri() as xs:anyURI
fn:namespace-uri($arg as node()?) as xs:anyURI

If $arg is the empty sequence, xs:anyURI("") is returned.
