This is indeed quite powerful, however in order to obtain the "path" to the current
node there still must be:

 1. The starting "/" for the root node. This could be obtained by changing the
expression to:

   <xsl:value-of select="for $e in ancestor::node() return name($e)"
                 separator="/" />

 2. The path has to include the current node. Therefore something like this will be
required:

   <xsl:value-of select="for $e in ancestor-or-self::node() return name($e)"
                 separator="/" />

  but this will not work for non-element nodes...

 3. Most important, positional information will not be included, so for example:

  /a/b[2]/c[3]

will produce:

 /a/b/c

 4. Maybe I'm wrong, but shouldn't this be: separator="'/'" ?
