+// RegisterDetail registers an error property key in a global registry, with a label.
+// The registry is used by the Details() function.  Registered error properties will
+// be included in Details() output, if the value of that error property is not nil.
+// For example:
+//
+//     err := New("boom")
+//     err = err.WithValue(colorKey, "red")
+//     fmt.Println(Details(err))
+//
+//     // Output:
+//     // boom
+//     //
+//     // <stacktrace>
+//
+//     RegisterDetail("Color", colorKey)
+//     fmt.Println(Details(err))
+//
+//     // Output:
+//     // boom
+//     // Color: red
+//     //
+//     // <stacktrace>
+//
+// Error property keys are typically not exported by the packages which define them.
+// Packages instead export functions which let callers access that property.
+// It's therefore up to the package
+// to register those properties which would make sense to include in the Details() output.
+// In other words, it's up to the author of the package which generates the errors
+// to publish printable error details, not the callers of the package.
