I am looking for best practices tom construct the XDM for Individual profile with many custom classes which will have additional details about the individual profile. I am trying to understand which approach will be better and on which aspect:
Embed the custom classes as field groups (as we have homeAddress under Person) within the individual profile
What aspects should we consider to decide when to choose which option? For example: If I go with a model following Option 1, then can I create a segment rule based on the attributes which belongs to the reference entity? Is there any restriction(s) on these 2 options?
