Further direction is provided for derivatives of personal names, particles in family names (i.e., da, de, della, von), medial capitals (i.e., MacDonald), and nicknames and epithets (i.e., the Iron Lady).
The Oxford English Grammar (ISBN 0-19-861250-8, published in 1996) states the following for how to write names (pp.97):
Proper nouns name specific people, animals, institutions, places, times, etc. They have unique reference, and in writing they begin with a capital letter; Bill Clinton, Jerusalem,Christmas, December.
It is clearly inappropriate, as defined by the standards of the Commonwealth Department of Finance and Deregulation, and in the Oxford English Grammar, to publish a person’s name in all-caps (i.e., MICHAEL LEUNIG). One may assume that when a person’s name is capitalised we are no longer referring to a human being and their personal name (but to a legal fiction and the legal fiction’s identity).
