Subject: [PATCH] closing bug #928 by dropping DOM document to xmlbuffer and
 re-reading into DOM each time a XSLT transform did occur.
 Yes, ugly, ugly, but no other possibility. Added output of
 XML after each transformation on YLOG_DEBUG level, run
 indexer with '-v debug' to see all transformations
