http://www.aixm.aero/schema/5.0/profile/gml4aixm.xsd AIXM_AbstractGML_ObjectTypesFeatures.xsd Base type for AIXM complex types that are NOT features or geometries. For example, OIL, FUEL, and Metadata. Derives from AbstractGMLType so that it can participate within many GML constructs if and as required. Retains only the optional gml:id attribute. This type serves to align AIXM with the upcoming GML v3.2 content model and patterns for features. As such, it removes any GML 3.1.1 deprecated feature properties (gml:location), and makes gml:id mandatory. It also derives from gml:DynamicFeatureType, as most if not all AIXM features are expected to be have some temporal properties modeled using either a snapshot or timeslice model. In addition, while the GML specification does not mandate that dynamic features derive from gml:DynamicFeatureType, many GML-aware applications may only detect a dynamic feature by this type hierarchy. Note that all temporal properties of gml:DynamicFeatureType are removed during this restriction, so that it can serve as a base type for both dynamic and non-dynamic AIXM feature types. Dynamic or temporal properties are added within AbstractAIXMDynamicFeatureType, which derives from this base type. Adds standard GML properties that will remain undeprecated in GML v3.2 (gml:name, gml:description), and any other common AIXM feature properties. Excludes temporal properties, lest there be some AIXM features that have none. Substitution head for AIXM features. Base type of AIXM Timeslices. Removes option attributes that are not used in AIXM. The efffectivity of the TimeSlice. Adds in the AIXM specific properties, such as 'interpretation'. Property indicating how the timeslice is to be interpreted. See the AIXM Temporality model for details. Used as unique key for the identification of the Time Slice concerned. See the AIXM Temporality model for details. Used for encoding corrections of a previously issued Time Slice. See the AIXM Temporality model for details. The start and end of life of the feature. See the AIXM Temporality model for details. Provided for convenience in the construction of this application schema, particularly when it is desired to define types derived by restriction. Derivation by restriction requires that all components that are used unchanged are copied down into the new type definition. As an alternative to including element declarations for all the standard object properties, a one line reference to aixm:StandardObjectProperties may be used instead. Only those standard GML feature properties that will NOT be deprecated in GML v3.2 are maintained. This therefore excludes gml:metaDataProperty. The global unique identifier of the AIXM feature
