OpenXR 1.13.0 fails to compile with Composition Layers 0.6.0 present in the project.

Each composition layer class tries to reference CompositionLayerManager.mainCameraCache but it’s not there:
Library\PackageCache\com.unity.xr.openxr@1.13.0\Runtime\CompositionLayers\OpenXRCubeLayer.cs(55,122): error CS0117: 'CompositionLayerManager' does not contain a definition for 'mainCameraCache'

Additionally, OpenXRLayerProvider is using an internal class:
Library\PackageCache\com.unity.xr.openxr@1.13.0\Runtime\CompositionLayers\OpenXRLayerProvider.cs(285,41): error CS0122: 'DefaultLayerData' is inaccessible due to its protection level

I presume composition layers has a newer unreleased update with these changes, but the version check for XR_COMPOSITION_LAYERS is still looking for > 0.5.0.

EDIT: Bug report confirmed as OXRB-410

I’m also seeing this. It’s preventing upgrading to 1.13.

The bug isn’t fixed in OpenXR, but XR Composition layers 1.0.0 is now available and doesn’t have this issue.
