how to remove a zone property

I have troubles how to find the proper command removing a property from a zone config.

Given -

zonecfg:lo-sol-j01> info

zonename: lo-sol-j01

zonepath: /zones/lo-sol-j01

brand: solaris

autoboot: true

anet 0:

  linkname: vnet0

  lower-link: net0

  configure-allowed-address: true

  mac-slot: 7

  vlan-id: 1032

capped-memory:

  physical: 64G

How can I only the remove lower-link property (if possible)? I don't get the syntax.

zonecfg:lo-sol-j01> select anet 0

zonecfg:lo-sol-j01:anet> remove value lower-link=net0

does not work.

And this removes the complete network config, which is way too much:

zonecfg:lo-sol-j01> remove anet lower-link=net0

I'm also very interested to run this as a one-liner.

$ zonecfg -z lo-sol-j01; "select anet 0; ...
