this is doable (we do support this in tracker and plan on adding support
to desktop files for this)

You would have a metadata type of struct
and have another field "children" that lists the child metadata names

Each child metadata will have its own def

Eg  for a struct type for Email:Address containg Contact:Name and
Contact:Email you would have:


[Contact:Name]
DisplayName=Contact:Name
Type=string

[Contact:Email]
DisplayName=Contact:Email
Type=string

[Email:Address]
DisplayName=Email:Address
Type=struct
Children=Contact:Name;Contact:Email;
