Can 'Attachment Circuits'-as-a-Service be a service type?

    augment /nw:networks/nw:network/nw:node:
              +--rw service* [service-type]
                 +--rw **service-type**                   identityref
                 +--rw sap* [sap-id]

As defined in RFC9408, 'service-type' are all connectivity services:

A SAP network topology can be used for one or multiple service types ('service-type'). Examples of supported service types are as follows:

L3VPN [RFC4364],
Virtual Private LAN Service (VPLS) [RFC4761][RFC4762],
Virtual Private Wire Service (VPWS) [RFC8214],
BGP MPLS-Based Ethernet VPN [RFC7432],
VPWS in Ethernet VPN [RFC8214],
Provider Backbone Bridging Combined with Ethernet VPN (PBB-EVPN) [RFC7623],
VXLAN-based EVPN [RFC8365],
Virtual Networks [RFC8453],
Enhanced VPN (VPN+) [I-D.ietf-teas-enhanced-vpn],
Network slice [I-D.ietf-teas-ietf-network-slices],
SDWAN [I-D.ietf-bess-bgp-sdwan-usage], and
Basic IP connectivity.

@lana-wu to report back on the need, including lack of clarity in the text.

For the ac-sap-figure attached, is the following is a valid example? If the example is correct, It seems to me, compared with the SAP model, the AC augmentation does not add more information here.

I suggest that you look at the example in https://datatracker.ietf.org/doc/html/[draft-ietf-opsawg-ntw-attachment-circuit-02](https://datatracker.ietf.org/doc/html/draft-ietf-opsawg-ntw-attachment-circuit-02#name-an-example)#name-an-example. Thanks.
