Section 2.a.i was the key area, but I guess the language does leave
enough room for some other mechanism to exist.

http://www.opensolaris.org/os/project/caiman/auto_install/ai_design/transport_data_diagram.pdf
seems to indicate that DHCP is a required component for x86 and SPARC.
 There is no recognition that all of the network configuration can be
performed for wanboot via network-boot-arguments.  I suggest adding a
note to the table on page 3 to the effect of "DHCP is not required on
a SPARC client that uses wanboot and has specified network parameters
via network-boot-arguments or interactive prompts."
