(ERROR) Non-escaped <...> in text in RFC XML

==== Initialization of the Status registry

This specification updates <<RFC5545>> by adding a Status value registry to the iCalendar Elements registry
located here: <https://www.iana.org/assignments/icalendar> and initializing it as per <<RFC5545>>.

located here: <hello>.

When running through xml2rfc:

_site/documents/draft-ietf-calext-subscription-upgrade.rfc.xml(383): Error: Did not expect element hello there, at /rfc/middle/section[10]/section[4]/section[1]/t[2]/hello
_site/documents/draft-ietf-calext-subscription-upgrade.rfc.xml(383): Error: Element t has extra content: hello, at /rfc/middle/section[10]/section[4]/section[1]/t[2]/hello
_site/documents/draft-ietf-calext-subscription-upgrade.rfc.xml(9): Error: Invalid document before running preptool.

Clearly the <hello> text became an element in XML RFC.

This issue is specific to metanorma-ietf, the other flavours keep the > < as is.
