NodeList and XmlSchema

[Benson Margulies]

WSCOMMONS-362 notes that NodeList is inherently non-thread-safe.
XmlSchema exposes a few APIs that accept and return NodeList's of
markup content for AppInfo and Documentation. Would anyone object to
changing those, incompatibly, to List (containing Nodes) for 1.4.3? I
might object myself, in which case these changes would have to wait
for a 1.5 or 2.0.
