XML mapping from access db

[BML]

I'm new to XML mappings and need some help. I need to map records from an access db to a specific XML format. The XDS has been provided. However being new to the XML mapping tools I'm struggling to execute the mapping correctly.

The problem is that I need to group the elements in the required layout. For example the db contains records with attributes that are repeated for every records like year and company. The XML layout must be grouped by year, company, title, person, address ect...

Could anyone offer some asssitance? I'm working with the Altova mapping tool.
