<!--[rfced] Section 3: May we update the YANG module as shown in
this diff file?
https://www.rfc-editor.org/authors/ietf-ospf-rfcdiff.html
The diff compares the current module to the output of the formatting
tool. Per guidance from Martin Bjorklund, this is using pyang to format the
module (as described on https://trac.ietf.org/trac/ops/wiki/yang-review-tools).
To be clear, with or without the formatting updates, the YANG module parses.
