Whatever input TLS passes into the signing algorithm. :-P I'm being
somewhat flippant, but the payloads aren't necessarily anything coherent.
See RFC8446, which defines the signing payload for a CertificateVerify
message. It's not a coherent protocol entity, rather it's all the context
necessary to meet the protocol's security requirements.
https://tools.ietf.org/html/rfc8446#section-4.4.3

Other drafts, like delegated credentials, define other payloads. (Although
it is unlikely anyone would actually want to batch-sign delegated
credentials.)

Perhaps "This document described a batched signature algorithm for TLS."?
