The netconfig.8 IMO documents this already:

"[...]
NETCONFIG MODULES
 [...]
       dns-bind
              This  module  writes  the  DNS nameservers as forwarders for the
              bind  nameserver  into  the  /etc/named.d/forwarders.conf  file.
              Please  verify that this file is included in the options section
              of /etc/named.conf, like:
              options {
                   #forward                first;
                   include                 "/etc/named.d/forwarders.conf";
              # [...]
              You can use the yast2 dns-server module  to  configure  bind  as
              forwarder.

       dns-dnsmasq
              This  module  writes  the  DNS nameservers as forwarders for the
              dnsmasq  nameserver  into  the  /var/run/dnsmasq-forwarders.conf
              file.  Please  verify,  that this file is set in the resolv-file
              keyword in the /etc/dnsmasq.conf.

Yes. It is documented in "man resolv.conf", but it makes sense to add it and
filter out at least 127.0.0.1 and ::1 from dnsmasq/bind forwarders list.

BTW: We are improving the NETCONFIG_DNS_FORWARDER documentation in sysconfig
variables and the man page in bug 580506 as well. All together, I'm going to
change to:

-## Type:        string
+## Type:        string(resolver,bind,dnsmasq,)
 ## Default:     "resolver"
 #
 # Defines the name of the DNS forwarder that has to be configured.
+# Currently implemented are "bind", "dnsmasq" and "resolver", that
+# causes to write the name server IP addresses to /etc/resolv.conf
+# only (no forwarder). Empty string defaults to "resolver".
 #
 NETCONFIG_DNS_FORWARDER="resolver"

 ## Type:        string
 ## Default:     ""
 #
 # List of DNS domain names used for host-name lookup.
+# It is written as search list into the /etc/resolv.conf file.
 #
 NETCONFIG_DNS_STATIC_SEARCHLIST=""

 ## Type:        string
 ## Default:     ""
 #
 # List of DNS nameserver IP addresses to use for host-name lookup.
+# When the NETCONFIG_DNS_FORWARDER variable is set to "resolver",
+# the name servers are written directly to /etc/resolv.conf.
+# Otherwise, the nameserver are written into a forwarder specific
+# configuration file and the /etc/resolv.conf does not contain any
+# nameservers causing the glibc to use the name server on the local
+# machine (the forwarder). See also netconfig(8) manual page.
 #
 NETCONFIG_DNS_STATIC_SERVERS=""

-## Type:        string
+## Type:        string(yes,no,)
 ## Default:     "yes"
 #
 # Defines whether to set the default NIS domain. When enabled and no domain
[...]
NETCONFIG_NIS_SETDOMAINNAME="yes"
