 * There are two types of parameters: Path parameters and query parameters.
 * 
 * Path parameters are the values that fill the asterisk placeholders in the route
 * definition of a ResourceNode.
 * 
 * Query parameters are the key-value pairs after a question mark which can be added
 * to each request, either by specifying them manually or as result of submitting an
 * HTML form with a GET as method property.
