Possibly. I did not check if the _current_ version of libxml2-utils
shipped with a symlink or a directory. If this is the case that it ships
a directory now:
 * preinst should check whether /usr/share/doc/libxml2-utils is a link
to the original target (and not another), if it is, then remove it.
 * prerm should reinstate it if there is an abort-upgrade condition.
 * there should be a conflict with current libxml2 version so that
libxml2 files are reinstalled (by pulling in a new version of libxml2).
No replaces necessary, since dpkg does not know they are the same files.

The last bit is optional (only if we are adamant about reinstalling
libxml2 documentation files).
