Why xfs is not permitted on bootable partitions in RHEL 7?

[Dhiraj Bhor]

Hi all,
I am new to this mailing list. I came across a issue with xfs while
installing RHEL 7.
When I created "custom layout" and created /boot partition with xfs file
system it shown me error as "/boot filesystem cannot be of type xfs".
Why xfs is not allowed on /boot partition?
Help me resolving this issue.
Thanks,
Dhiraj
