In ECF 4, we mapped both person and organization aliases to ecf:Alias. 

In ECF 5, we mapped person aliases to nc:PersonName and organizational aliases to nc:OrganizationAlternateName.

Unfortunately, the cardinality for nc:Person/nc:PersonName is 0,1 which prevents representing both the true name and one of more aliases.

A simple fix to ECF 5.0 would be to relax the cardinality on nc:Person/nc:PersonName to 0,unbounded to allow one or more aliases.

Indicate alilas/aka/etc with j:PersonNameCategoryCode
