In Caid that's the achievement an Award of Arms gets. A Grant of Arms gets a helm and manteling and a Patent of Arms gets a helm, manteling, supporters and can have a crest.

The achievements are explained on the Caid Scribes page

http://scribes.sca-caid.org/

in the section for each award.

I think it's pretty neat but I'm sure it's different in each Kingdom. :)
