The ARM isn't to clear about all of these in one place and jumps round a 
lot. It does refer to RFC 1035 also.

As for "minimum", it is documented in the ARM:

	 The last field in the SOA is the negative caching TTL. This 
	 controls how long other servers will cache no-such-domain 
	 (NXDOMAIN) responses from you.

	 The maximum time for negative caching is 3 hours (3h).
