Limit resource selection to same namespace as XR

[tvandinther]

What problem are you facing?

I want to get resources scoped to the same namespace as the composite resource. Currently I can only scope this to a static namespace field or search cluster-wide.

How could this Function help solve your problem?

Allow a namespaceFromCompositeFieldPath or similar field so that you can specify namespaceFromCompositeFieldPath: metadata.namespace

Facing the same problem.

It would be breaking, but the following would fit well with what's in label selector. It would also support taking the namespace from somewhere in the composite resource's spec.

namespace:
  type: FromCompositeFieldPath
  valueFromFieldPath: metadata.namespace

namespace:
  type: Value
  value: crossplane-system
