Where to find documentation of CoreStorage on-disk structures?

I've found APFS documentation (Apple-File-System-Reference.pdf) and HFS+ documentation (Technical Note TN1150 HFS Plus Volume Format). Is there similar documentation for the on-disk structures and format of CoreStorage logical volumes?

There is not. Given Apple’s current path, this is unlikely to ever be documented for third parties.

AFAIK, "LV groups are made up of PVs - a PV must be partitioned with the GPT partitioning scheme (GUID Partition Table) and get its own identifier called GUID. In addition, each of them keeps some information about the LV group."
