  If you look at xsltApplyStylesheetInternal() code, there is a bunch
of processing needed before and after launching the recursive evaluation
done on the root node by
   xsltProcessOneNode(ctxt, ctxt->node, NULL);
I don't think it is wise to try to attempt a direct processing, and
the document passed to xsltApplyStylesheet() will be modified, you
may not want that to happen to a subtree. So I suggest building a new
document with a copy of the subtree as the cleaner approach.
