Build PVXS from
https://github.com/epics-base/pvxs
As a result you’ll have the new C++ PVXS library, command line tools pvxget, pvxmonitor, … and the softIocPVX mentioned by Jure

Thank you Jure.
Can anyone point to any examples of this in github, etc?

Hi,
You need to build your IOC with a recent version of PVXS. This will serve records over PVAccess using the newer QSRV2, which handles the lsi record the way one would expect. For a quick test, use softIocPVX that comes with the PVXS module.
Best,
Jure
