Within an address, otheraddr is a wrapper for parts of an address other than street, pob, postcode, city, state, country, phone, fax, and email, all of which have elements specific to their content.

In early versions of DocBook, address was not allowed to contain character data (it was a database-like collection of fields). In that context, a wrapper was necessary for any random pieces of information that might be required for an address. With the introduction of character data directly in the address element, otheraddr may have lost most of its raison d’être.
