/**
 * Create a new container scope using the results of a given query as its contents.

 * @param id
 *          Human-readable name of the scope, typically used to identify where the scope was created. Useful for debugging.

 *          The outer scope of the new scope.
 * @param context
 *          The context
 * @param query
 *          The query that defines the scope's contents
 * @param nameFunctions
 *          The name functions to apply
 * @param originalResource
 *          The original resource
 * @param caseInsensitive
 *          indicates whether the new scope shall be case insensitive
