How to enforce `maxImageRectWidth`, especially for non-projection layers?

[ajul]

1. XrViewConfigurationView specifies maxImageRectWidth and maxImageRectHeight but no enforcement is explicitly specified. Should the runtime return XR_ERROR_SWAPCHAIN_RECT_INVALID if the application specifies a XrSwapchainSubImage that is larger than these limits?

2. It seems that maxImageRectWidth and maxImageRectHeight only apply to XrCompositionLayerProjection. Would it be possible to have some way for the runtime to limit the subimage extent for other layer types, such as XrCompositionLayerQuad? Or will the only mechanism for this be to limit the maximum extent of the entire swapchain image via XrSystemGraphicsProperties.maxSwapchainImageWidth and Height?
