<xsl:value-of select="?"/> always returns the first value when the select
returns a node-set so this behavior is not exceptional. Nor is it difficult
to understand that the particular form of <xsl:variable ...> returns
a result tree fragment. But what I find difficult myself is why the 
result tree fragment can be placed in the predicate since chapter 11.1
specifically prohibits this:

   "In particular, it is not permitted to use the 
   /, // and [] operators on result tree fragments"

My guess is that the predicate [$n] is being converted to a boolean
value of true and the predicate therefore selects all items. The 
<xsl:value-of> is merely returning the first item in the node set.

Thats my theory.

Dan
