Both is fine, it depends if you need a ramdisk or not to actually  
complete the boot.
For out purposes:
  vmlinux = 64bit ELF
  vmlinux.strip = strip version of vmlinux
  zImage = 32bit ELF small executable that contains a compressed  
version of vmlinux.strip in the data segment.
           The 32bit executable then uncompresses the vmlinux.strip  
and leaps at it.
  zImage.initrd = a zImage that also contains a ramdisk as well as  
the vmlinux.strip
The xen code that loads a Dom0 can be any of the above images.
If you want a ramdisk the only option you have is zImage.initrd

For completeness:
  vmlinuz = vmlinux.strip that is compressed

is _not loadable from Xen and usually used by yaboot.
