Wouldn't it be helpful, and symmetric, to have an function in the specification
for decoding URIs?

  fn:decode-uri($uri-part as xs:string?) as xs:string

I have seen that existing XQuery implementations already provide something
equivalent:

  http://exist-db.org/exist/functions/xmldb/decode-uri
  http://www.zorba-xquery.com/html/modules/zorba/xdm/atomic/uri

Decoding a URI via plain XQuery feels like a pretty tedious job, and I think it
shouldn't be too hard to add the functionality to others implementations, so
I'm wondering why this function hasn't made it to the standard yet.

I have just found two discussions that also seem to focus on this issue..

 
http://markmail.org/thread/knd246eiayderbd6#query:+page:1+mid:knd246eiayderbd6+state:results
 
http://markmail.org/thread/nt3hjtdizvz2ltvx#query:+page:1+mid:nt3hjtdizvz2ltvx+state:results

..but the argument "difficulty in the detail of specifying it", as Michael Kay
put it, didn't really convince me, because functions like format-date() appear
much more sophisticated to me. Regarding the use cases, I have one for myself,
and the existing implementations and discussions seem to prove that there is
some need.

Sorry for bothering, thanks for reading,
Hannes
