Query parameters
The properties that should be included. The parameter value is a comma-separated list of property names.
The optional f parameter indicates the output format which the server shall provide as part of the response document. The default format is GeoJSON.
The profile to be applied to a given request
The optional lang parameter instructs the server return a response in a certain language, if supported. If the language is not among the available values, the Accept-Language header language will be used if it is supported. If the header is missing, the default server language is used. Note that providers may only support a single language (or often no language at all), that can be different from the server language. Language strings can be written in a complex (e.g. "fr-CA,fr;q=0.9,en-US;q=0.8,en;q=0.7"), simple (e.g. "de") or locale-like (e.g. "de-CH" or "fr_BE") fashion.
