Set sunset link relation type as http response header field in api management policy

Question

I want to set The Sunset Link Relation Type as a Http Response Header field along with the Sunset response Header field. I am using the set-header policy in the outbound policy of an api(GET Operation).

I have reference the documentation below:

https://datatracker.ietf.org/doc/html/rfc8594#:~:text=If%20communicated%20as%20an%20HTTP%20header%20field%2C%20it%20might%0A%20%20%20look%20as%20follows%3A

Following the same if i set the Sunset link relation type, i get the below error while trying to save the policy

If i remove <, > in the same then it allows me to save. With the less than and greater than it does not allow me to save the policy.
Below is the response for a test that i did:

Is this the correct usage or am i missing something here. Please suggest.

@suvra jyoti On the APIM usage part on setting the header you are following the right way but the value you enter cannot be assigned as you see in the error message
Looking into the section 9 I do see the example provided as Link: <http://example.net/sunset>;rel="sunset";type="text/html"
The suggestion would be using the Named Value for your requirement.
