Non-Defining Vs Defining Relative Clause: Realisation

Halliday & Matthiessen (2004: 402):
In written English, a non-defining relative clause is marked off by punctuation — usually commas, but sometimes by being introduced with a dash; whereas a defining relative clause is not separated by punctuation from its antecedent. This in turn reflects the the fact that in spoken English, whereas the defining relative clause enters into a single tone group with its antecedent, a non-defining relative clause forms a separate tone group. Furthermore, the primary and secondary clauses are linked by tone concord: that is to say, they are spoken on the same tone.
