There's no need to go via strings.

Assuming the 'references' attribute is declared IDREFS (it should be),
you can use the `referent' function, which maps over all the values:

  (referent (attribute-value "references" (current-node)))

will return the node-list you're after.

I'm not sure if it's possible to do this with non-IDREF attributes,
though (for example, pointers into another grove).
