RecipeElements defines a folder for all RecipeElements that are part of the recipe.
RecipeId defines a unique identifier of a recipe.
RecipeName defines a user-readable name of the recipe.
RecipeFile is a file that contains the recipe in a vendor-specific format. If a client uploads the file, the recipe elements can be also part of the AddressSpace. But the Method AddRecipeElement and RemoveRecipeElement should not be used. So a recipe uploaded via file transfer cannot be modified via AddRecipeElement or RemoveRecipeElement. This avoids that there is another version of the recipe in the file and the server.
