Integration, IV, p. 79, § 5. Measurable functions and sets
Let be a locally compact space, a measure on , and a -measurable subset of . A mapping of into a topological space is said to be -measurable if it satisfies the equivalent conditions of Prop. 15.
If is locally -negligible, then every mapping of into is therefore -measurable.
Bourbaki puts the proof directly after the statement, so what is above is the statement and its proof together.
