Syslinux - Oct 2018 - Using wimboot with syslinux UEFI

I am trying to load a WinPE boot image using wimboot, and failing. The 3 files
appear to load successfully (the output "Encapsulating ...
<filename>" is displayed for each file, taking a few minutes on the
.wim file as expected based on the size), but then the workstation just reboots,
and I don't see output after that.

Has anyone successfully loaded WinPE using wimboot with syslinux.efi? Ideas on
why it's not working for me?

- boot loader is /syslinux-6.03/efi64/efi/syslinux.efi
- wimboot version 2.6.0
- menu entry:
LABEL WinPE
MENU LABEL + Windows PE
KERNEL linux.c32
APPEND wimboot gui initrdfile=bcd,boot.sdi,boot.wim

I haven't personally tried but unless things are built for UEFI boot,
they won't work.  If wimboot isn't ready for UEFI, it won't work. 
If
the combination of the bcd, boot.sdi and boot.wim aren't ready, it
won't work.
