+Test data for the validation of extensions in the context of external tilesets.
+
+(This is a special aspect of https://github.com/CesiumGS/3d-tiles-validator/issues/231 ).
+
+Each of these data sets consists of a `tileset.json` that refers to an `external.json`.
+
+They use a "dummy" extension called `VENDOR_example_extension` to check the validation
+of the `extensionsUsed` propery of a tileset. (This means that the validation will
+always at least create one warning, because the extension is not supported).
+
+In the following, the term..
+
+- 'declared' means that a tileset declares the extension in its `extesionsUsed`
+- 'contained' means that the tileset actually contains such an extension object in its `extensions`
+
+These cases are considered:
+
+- `declaredInBothContainedInExternal`: This is valid. The external tileset contains it and declares it. The main tileset also declares it (because it refers to one that contains it). 
+- `declaredInBothContainedInTileset`: This valid, but causes a warning. The external tileset does not have to declare it if it does not contain it.
+- `declaredInExternalContainedInExternal`: This is invalid. The main tileset also has to declare it when it refers to one that contains it.
+- `declaredInExternalContainedInTileset`: This is invalid. The main tileset has to declare it if it contains it.
+- `declaredInNoneContainedInExternal`: This is invalid. Both tilesets have to declare it when the external one contains it.
+- `declaredInTilesetContainedInExternal`: This is invalid. The external one also has to declare it when it contains it
+- `declaredInTilesetContainedInTileset`: This is valid. Only the main tileset has to declare it if only the main tileset contains it.
