Description Oliver Hallam 2008-04-02 16:38:19 UTC 
F&O 11.2.4:

fn:namespace-uri-from-QName($arg as xs:QName?) as xs:anyURI?

Summary: Returns the namespace URI for $arg as an xs:string. If $arg is the empty sequence, the empty sequence is returned. If $arg is in no namespace, the zero-length string is returned.

Surely the summary should read xs:anyURI and not xs:string.  Also one could argue that the term "zero-length string" should read "zero-length xs:anyUri", or "xs:anyUri whose value is the zero-length string", but that is just picking hairs.

On 22 April 2008 the WG accepted this bug and directed the editor to raise the appropriate erratum.

To the originator: please close if you are content with this resolution.
