Detailed Description

SDK 1.8 capability resolving an extension's native preview layer for selection sync.

Discover this optional interface with qobject_cast on ExtensionHost::lifetime(). IProject::showPreview() with previewStyle.asFeatureLayer creates a host-owned temporary GIS layer. This capability names that layer's runtime attachment and maps each accepted collection feature to its native FID, so an extension can read and replace the layer's selection through IViewControls and observe LayerSelectionChanged on IViewEvents. Existing SDK interfaces and their binary layouts remain unchanged.
