Inside a family, we can have variables or families.
The "type" for family "manual" became unecessary because container an other family, so it's not a variable.
In disabled attribute, it's better tu use relative path (we will see the reason in an other slide).
The "manual" mode structural descriptions are write in a new files to separate things. But Rougail will concatenate variables and families.
We create a family, which will contain other variables.
This family has:
- a description
- a type
As there is no variable inside this family, the type is mandatory. Without it, Rougail will create a variable.
In fact, this family will be deleted by Rougail too because it is empty.
