Declare Index for Embed classes or Data Classes?
For example,
My work objects are in: MyApp-Work-TestApp
MyApp-Data-TestAppDetails (abstract)
Embed-MyApp-Work-TestApp (abstract)
If I want to expose many .CaseDetails (page) properties into a Declare Index rule, is the data or embed class better?
My understanding is data class is reusable and embed classes are specific to the work object and non reusable. So it's there any advantage to using embed classes?
