incomplete list of SRVCTL commands

As I have to dig into srvctl more than I liked to do, I figured the documentation is not complete (at least for my installation of 11.2.0.2):
the Documentation for srvctl upgrade claims

The srvctl upgrade database command upgrades the configuration of a database and all of its services to the version of the database home from where this command is run.

But there is a 2nd option missing totally:

Usage: srvctl upgrade model -s <source-version> -d <destination-version> -p {first|last} [-e <name>=<value>[,<name>=<value>, ...]

in more detail:

srvctl upgrade model -h



Upgrade the Oracle Clusterware resource types and resources.



Usage: srvctl upgrade model -s <source-version> -d <destination-version> -p {first|last} [-e <name>=<value>[,<name>=<value>, ...]

   -s <source-version>      Version from which to upgrade

   -d <destination-version> Version to which to upgrade

   -p {first|last}          Whether the command is called from the first upgraded node or the last upgraded node

   -e <name>=<value>[,<name>=<value>, ...] Additional name value pairs for upgrade

   -h                       Print usage

In general thsi should only be needed during an CRS upgrade, as part of root.sh script. Nevertheless, as it's there it should be documented. Especially the -e parameter seems to be worth more information than the -h docu provides.
