I'm working on the definitions of the node types in my application.
After reading the spec, there's one thing that didn't come across
clearly (well, so far anyway). If I define a node with a required
type of child node, can that child's primary type be a sub-type of
the required node?
For example, say I have the following nodes defined
nt:base
|
|--- Vehicle
| |
| |--- Car
| |
| |--- Bicycle
| |
| |--- Boat
|
|--- Person
And I want to require a person to have a "primaryVehicle" child. I'd
like that type to be anything in the Vehicle hierarchy. So can I
define the type to be Vehicle, or do I need to give the list of
Vehicle sub-types?
I'm assuming there's no way to define a type as abstract... if there
were, I'd make Vehicle in the above example abstract.
Thanks,
Mark
