This is exactly what I started with, but it didn't work, which is why I
tried some other things. I have reverted to this configuration.
Can I omit the "rewrite ..." on both sides?
Here's the status on both sides:

Hi Jerry,
I would update the config as follows (if you're just doing a basic P2P
pseudowire, go for the KISS approach):
ASR9K:
interface TenGigE0/0/1/0.95 l2transport
encapsulation dot1q 95
rewrite ingress tag pop 1 symmetric
mtu 9118 ! Needs to be +14 for Ethernet +4 for VLAN tag on IOS-XR
l2vpn
xconnect group mpls1
p2p test1
interface TenGigE0/0/1/0.95
neighbor ipv4 10.100.66.1 pw-id 95
ASR920:
interface TenGigabitEthernet0/0/25
mtu 9100 ! Excludes Ethernet and VLAN tag on IOS-XE
no ip address
cdp enable
service instance 95 ethernet
encapsulation dot1q 95
rewrite ingress tag pop 1 symmetric
xconnect 10.100.25.11 95 encapsulation mpls
Then remove this unless you want to set up a VPLS/P2MP/MP2MP L2 VPN:
l2vpn xconnect context test1
member TenGigabitEthernet0/0/25 service-instance 95
member 10.100.25.11 95 encapsulation mpls
If that doesn't work provide us with full the output of "show l2vpn
xconnect pw-id 95 detail" from the ASR9K/IOS-XR and equivalent from
the ASR920/XE.
