Despite no common, enforceable widespread regulation, heraldry has remained consistent across Europe, where tradition alone has governed the design and use of arms. Some nations, such as England and Scotland, still maintain the same heraldic authorities which have traditionally granted and regulated arms for centuries and continue to do so in the present day. In England, for example, the granting of arms is and has been controlled by the College of Arms. Unlike seals and other general emblems, heraldic "achievements" have a formal description called a blazon, which uses vocabulary that allows for consistency in heraldic depictions. In the present day, coats of arms are still in use by a variety of institutions and individuals: for example, many European cities and universities have guidelines on how their coats of arms may be used, and protect their use as trademarks as any other unique identifier might be. Many societies exist that also aid in the design and registration of personal arms.
