Clause Complex With Non-Finite Hypotactic Elaboration

Every night, at exactly 21:53, the Chief Yeoman Warder of the Tower emerges from the Byward Tower	wearing his long red coat and Tudor bonnet	and carrying a candle lantern and the Queen's Keys
a	= b
	1	+ 2

Reasoning:

Consider the finite agnates of the dependent clauses in the following, where they are presented as enclosed within the primary clause:

Every night, at exactly 21:53, the Chief Yeoman Warder of the Tower << who wears his long red coat and Tudor bonnet and carries a candle lantern and the Queen's Keys >> emerges from the Byward Tower.

The finite agnates of the dependent clauses are clearly non-defining relative clauses, which are instances of hypotactic elaboration — not enhancement.
