The attribute tabs enable the mapping of attributes for the migration. Effectively this is a simple mapping of the Attribute Name in DOORS to the Attribute Name in DOORS Next. We assume that the base types are the same construction. This allows simple mapping rules to migrate your information.
For enumerations, the ReqmtAttrValues allows you to map the values of the DOORS elements to DOORS Next. This allows name or formatting change to occur and a remapping to occur.
