<variable name="var" select="/node1/node2" /> returns a node list.

<variable name="var">
   <value-of select="node1/node2" />
</variable> returns RTREEFRAG and should return also a node list.

I include a real sample first XSLT works, second XSLT raises error:
Can not convert #RTREEFRAG to a NodeList!
