> 1. Remove code for dissecting 17.2170.3 thru 17.2170.9.

Correct.  2170 only has the 2 sub-options.  Note that 17.2170.1 and 17.2170.2
are different than 17.2171.1 and 17.2171.2 ....  (Table 15 vs Table 16 in
CL-SP-CANN)

RFC 3495 (http://tools.ietf.org/html/rfc3495), section 5.5 lays out the
requirements for this sub-option.  It does need to be a valid FQDN (much like,
say, DHCPv4 option 15), with the additional requirement that it MUST be all
caps.  (BTW: the name "BASIC.1" has special meaning in this context, as does
"BASIC.2", "HYBRID.1", and "HYBRID.2".  They are still encoded as normal FQDNs
however.)
