Hm, let me see - this is going to be a bit tough :)
Currently, wicked supports wired Ethernet, VLANs, bridges, bonds, wireless
(no EAP mode yet, though), openvpn, and to some degree GSM modems. For
most of these, the set of properties accessible exceeds those of
NetworkManager by far.
In terms of address configuration, it supports dhcp4 and dhcp6, as well as
IPv4 zeroconf (in addition to static and ipv6 autoconf). You can mix addrconf
modes (eg configure a NIC with DHCPv4 plus two static routes).
The layered approach tries to decouple the settings of each layer. For
instance, you can take down the DHCPv6 agent and bring up the DHCPv4
agent on an interface without having to cycle it completely. Same for
adding a bridge port, or removing one NIC from a bond, or for changing
the offload parameters on an Eth device.

Yes, I had been thinking of something like this as well.

Hm, not "readable" in the sense of nice HTML. There's a schema definition
in the source code which hopefully goes a long way to give you an idea of
how it works.
