It is common for elected officials to have offices at the legislature and in their constituencies, each with their own address and telephone numbers. It is also possible for an elected official to have a telephone number that is associated with his seat but that is not tied to either office, e.g. a mobile number.
As in #5, given that the former case is very common, and to make telephone lookups more predictable, telephone fields should be on Address documents only.
