I read Table 8-1 as :
one can choose between '' and '0' for "Indirect IPv6 unicast routes"
especially because of below...

Yes. did try:

SW2(config)#ipv6 rou?
% Unrecognized command
SW2(config)#ipv6 ?
  flowset         Set flow label random for originated packets
  general-prefix  Configure a general IPv6 prefix
  hop-limit       Configure hop count limit
  host            Configure static hostnames
  icmp            Configure ICMP parameters
  local           Specify local options
  nd              Configure IPv6 ND
  neighbor        Neighbor
  radius          RADIUS configuration commands
  source-route    Process packets with source routing header options
  tacacs          TACACS configuration commands
  traffic         Configure traffic parameters

SW2(config)#ipv6


I feel like considering there _might_ be a bug...
But it's be faster if someone just points out the problem I'm having ;-)
If not I'll try the vendor tomorrow.
I could maybe try to get a default via RA - not the first choice.

reason for trying IOS 15...

PS: showing the ipv6 routes works as advertised (i have none) :
SW2#sh ipv6 static
IPv6 Static routes Table - Default
Codes: * - installed in RIB, u/m - Unicast/Multicast only
       U - Per-user Static route, N - ND Static route
       P - DHCP-PD Static route
       R - Rhi Static route
SW2#
