Avoid spurious Analyzer message when deploying external objects (e.g. Foo__x)
If you create a new org, add an External Data Source, add External Objects, and deploy to a target (source control), you will get this spurious analyzer message:
"Some standard object fields which don't exist in the target organization are being deployed, which indicates they might use features not enabled in the target. You need to remove these from the deployment, otherwise it's likely to fail."
and all your external objects are enumerated, e.g.
These are not standard objects, and, as they are new, would of course not be in the target. Analyzer is being too "discerning"
