# Prior to development of this test, 4XSLT was not properly determining the
# string-value for elements in a node-set that was generated from a result
# tree fragment with exslt:node-set. Only text node children of the elements
# were picked up; other text node descendants were not. This was fixed by a
# minor patch to Ft/Xslt/RtfWriter.py.
