Yes, this is a known problem of BIND-8.

There is a fix (appended) to prevent the BIND-8 named-xfer writing
out a zonefile with syntax errors, but this will still not produce
the correct DNSSEC zonefile, because BIND-8 does not understand the
special handling of the DS.

We have an NSD version of named-xfer, but it is not yet released (it
will soon be after quality assurance checks).

	Firstly one really shouldn't attempt to use DNSSECbis
	unless *all* the servers for the zone are DNSSECbis aware.

	I'm tempted to leave this here just so that the zone transfer

	That being said I feel the following patch is cleaner.
