bind

optional

Binds a specific value to a property when overriding a property defined by a parent concept.

Example

structure (Business) {
property (businessCategory) {
type (BusinessCategory)
max (Many)
}
...

If you then define Restaurant as an extension of Business, you can force the businessCategory property to only hold the specific Restaurant value, which you would specify with bind.

structure (Restaurant) {
extends (Business)

property (businessCategory) {
override bind (Restaurant)
}

...
}
