Schematron validation Property element may not carry both a reference to an object and contain an object. Property element must either carry a reference to an object or contain an object.

Area of precipitation to be observed on the ground. Area is modelled as continuous patch of abstract earth surface (without topology) defined by an exterior Ring and 0..n interior Rings ("holes").

Exactly one rain (water) phase can be defined for the area.

The continuity (as in continuous rain) and the showeriness (as in rain showers) of the rain can both be specified as a floating point number between 0 and 1.

Precipitation areas may contain 0..n inner areas with different rain phase, continuity and/or showeriness qualities. These area are defined by using innerArea element which is a property containing or referring to another SurfacePrecipitationArea object. The exterior of the contained area object must be completely inside the exterior and not even partly cover the area inside any of the interior Rings of the parent object. If a value for any of the qualities is not given, it is assumed to be the same as in its parent.

To be used when using this object type as property of n GML object type according to the GML object-property-association model (it is not allowed for GML Objects to contain other GML Objects as direct children). Enables referencing to an existing object using xlink:href attribute.

Area of cloud coverage including cloud type and coverage in percentage, eighths or cloud amount abbreviations according to the ICAO's "Annex 3 to the Convention on International Civil Aviation: Meteorological Service for International Air Navigation".

Cloud areas may contain 0..n inner areas with different cloud type and coverage qualities. These area are defined by using innerArea element which is a property containing or referring to another CloudArea object. The exterior of the contained area object must be completely inside the exterior and not even partly cover the area inside any of the interior Rings of the parent object. If a value for any of the qualities is not given, it is assumed to be the same as in its parent.

Textual weather forecast for the given area with one or more semantically divided sections (rain, wind, temperature conditions and so on). Forecast target area is modelled as continuous patch of abstract earth surface (without topology) defined by an exterior Ring and 0..n interior Rings ("holes").

Text forecast areas may contain 0..n inner areas with different qualities. These area are defined by using innerArea element which is a property containing or referring to another GroundTextForecast object. The exterior of the contained area object must be completely inside the exterior and not even partly cover the area inside any of the interior Rings of the parent object. If a value for any of the qualities is not given, it is assumed to be the same as in its parent.

A general note regarding a specified surface area and time.
