/* This is a series of commands that could be used under the right

   env to modify the xml_nodes table to make the nodedata column

   smaller so that it can be indexed.  How this would work without

   losing data for rows that are > 3000 chars is not yet fully worked out,

   so do NOT apply this indiscriminately.
