The generated IDs would also let you get to the node you were after,
if you defined a key that indexed nodes by their generated ID:

<xsl:key name="generated-id" match="node()|@*" use="generate-id()" />

If you had your resolve-xpointer template returning a result tree
fragment of 'node' elements for the value of the $members variable,
you could use:

  key('generated-id', exsl:node-set($members)/node)

to get your list of the actual nodes themselves.

It's quite a large key table, though (!) which is why using an
extension function to return the nodes themselves is possibly a
cleaner way to do it.
