/servers/id/action APIs have incorrect details

On http://api.openstack.org, with the Compute API, there are several API calls that all have the same signature:

POST
v1.1/{tenant_id}/servers/{server_id}/action

For example:
Change a server's password.
Reboot the specified server.
Rebuild the specified server.
Resize the specified server.
Confirm a pending resize action.
Cancel and revert a pending resize action.
Creates a new image.

However, the docs do not describe the name of the action in each case (e.g., changePassword, reboot, rebuild), which I thought would appear if you click on "details".

Also, in every case, it specifies the same parameters:

tenant_id: The ID for the tenant or account in a multi-tenancy cloud.
server_id: The UUID for the server of interest to you.

But that can't be correct, since the different API calls should have different parameters.
