Digital Services Act compatability

[patmmccann]

So there is a legal requirement that some publishers tell a user, perhaps from their cmp, or perhaps using their own tech, or perhaps from say the adchoices icon, the reason an ad was selected for them. See https://iabtechlab.com/iab-tech-lab-releases-for-public-comment-specification-for-dsa-transparency/ .

It seems a publisher can basically pick one of two options: (a) let (and trust under threat of govt penalty) that the fenced ads will render the DSA information or (b) not allow fenced frames

A is undesirable to many pubs bc the amount of trust to extend to the advertising community in general without a validation mechanism is quite large. B seems undesirable as well for obvious reasons.

How can a publisher used fenced frames but also prevent responses without dsa information from rendering? Assuming that is possible, how can a publisher used fenced frames but also prevent responses with insufficiently detailed dsa information from rendering?
