XSLT 1.0 [1] says:

   A result tree fragment represents a fragment of the result tree. A
   result tree fragment is treated equivalently to a node-set that
   contains just a single root node.

EXSLT [2] says:

   The exsl:node-set function returns a node-set from a result tree
   fragment (which is what you get when you use the content of
   xsl:variable rather than its select attribute to give a variable
   value).

XPath 1.0 [3] says:

   XPath operates on an XML document as a tree.

and [4]:

   The root node is the root of the tree.

RTF nodes are not node-set nodes.

You're not creating node-set datatype nodes until you use
exsl:node-set() to turn the RTF into a node-set (or you use xsl:copy-of
to copy the RTF to the result tree).

About all you can do with an RTF as an RTF is use its string value.

The result of exsl:node-set() has the same general structure as a
document in that it has one root node, but that root node could have
multiple element node children (unlike an XML document).
