can't call the outer most return value by name

Odd, one can see <R> but not access by it. Run this:

declare function local:K($x){ switch ($x) case 2 return <R><name>N</name><o><name>Y</name></o></R> default return() }; " A",local:K(2)//*:R, " B",local:K(2)/o/name, (: shows we are already at the root :) " C",local:K(2)/., (: reveals R is really in there, but can't be called by name :) " D",local:K(2)/./R

What's the deal?

Hi Jidanni,

<R/> needs to be accessed via the self axis, e.g.:

  <R><name>N</name><o><name>Y</name></o></R>/self::R

The following query..

  local:K(2)/R

..is a shortcut for

  local:K(2)/child::R

Hope this helps, Christian
