/**
* A mapping between addressbook properties and ldap attributes.
*
* Each addressbook property can map to one or more attributes. If
* there is no entry in preferences for a field, the getters generally
* return null; empty strings are passed through as usual. The intent is
* that properties with a non-zero number of attributes can be overridden for
* a specific server by supplying a zero-length string. For this to work,
* most callers are likely to want to check for both success and a
* non-empty string.
*
* Note that the one exception to this pattern is getAttributes, which
* throws NS_ERROR_FAILURE for non-existent property entries, since
* XPConnect doesn't like returning null arrays.
*
* Note that each LDAP attribute can map to at most one addressbook
* property. The checkState method is a useful tool in enforcing
* this. Failure to enforce it may make it impossible to guarantee
* that getProperty will do something consistent and reasonable.
*
* Maybe someday once we support ldap autoconfig stuff (ie
* draft-joslin-config-schema-11.txt), we can simplify this and other
* code and only allow a property to map to a single attribute.
