Fundamentally, wouldnt that require the said IXP to be able to send full internet feed (v4 + v6) beyond the peering LAN routes?
I don't think so, I'm sure there are so many upstream providers selling IP transit without having nor sending the full internet feed.
In some jurisdictions, the regulators require Transit Providers to have some sort of ISP license to sell such capacity.
Totally right..

Can an IXP sell traffic? This is a rhetorical question. I know that it can... In fact, it is obvious that it can.
It is quite common to see several companies buying and selling traffic through IXPs. But whenever I have been involved with more serious companies, it was common for this type of traffic to be over a Bilateral VLAN between the Downstream and Upstream, and the ASs involved were from the operations themselves (different from the ASN used by Route-Servers).
But I have seen a reasonably large scenario in which the IXP operator, maintaining the MLPA LAN with the pair of Route-Servers, adds another participant with the SAME ASN as the route-servers, and through this participant starts to sell traffic.
This seemed very strange to me! And that is why I came to ask if this is correct or not. I would appreciate any guidance on the subject.
In fact, there were other aggravating factors that worried me: - The IXP activation information itself (VLAN, IPv4/IPv6, Route-Servers, etc.) was indistinguishable from the information in the transit BGP session. And the extra Billing information for anything sent by the transit was not explicit. - The routes reported exchanged by this transit had the ASN transparency function in the AS-Path.
