Content
- Choice [0..*]
- gml:DynamicFeatureStates are captured by time-stamped instances of a feature. The content model extends the standard gml:AbstractFeatureType with the gml:dynamicProperties model group. Each time-stamped instance represents a 'snapshot' of a feature. The dynamic feature classes will normally be extended to suit particular applications. A dynamic feature bears either a time stamp or a history.
- gml:DynamicFeatureCollectionA gml:DynamicFeatureCollection is a feature collection that has a gml:validTime property (i.e. is a snapshot of the feature collection) or which has a gml:history property that contains one or more gml:AbstractTimeSlices each of which contain values of the time varying properties of the feature collection. Note that the gml:DynamicFeatureCollection may be one of the following: 1. A feature collection which consists of static feature members (members do not change in time) but which has properties of the collection object as a whole that do change in time . 2. A feature collection which consists of dynamic feature members (the members are gml:DynamicFeatures) but which also has properties of the collection as a whole that vary in time.

Attributes
| Name | Occ | Type | Description | Notes |
|---|---|---|---|---|
| owns | [0..1] | xsd:boolean | Default value is "false". from group gml:OwnershipAttributeGroup | |
| xlink:type | [0..1] | xsd:string | Fixed value is "simple". from group xlink:simpleLink | |
| xlink:href | [0..1] | xsd:anyURI | from group xlink:simpleLink | |
| xlink:role | [0..1] | xsd:anyURI | from group xlink:simpleLink | |
| xlink:arcrole | [0..1] | xsd:anyURI | from group xlink:simpleLink | |
| xlink:title | [0..1] | xsd:string | from group xlink:simpleLink | |
| xlink:show | [0..1] | Anonymous | The 'show' attribute is used to communicate the desired presentation of the ending resource on traversal from the starting resource; it's value should be treated as follows: new - load ending resource in a new window, frame, pane, or other presentation context replace - load the resource in the same window, frame, pane, or other presentation context embed - load ending resource in place of the presentation of the starting resource other - behavior is unconstrained; examine other markup in the link for hints none - behavior is unconstrained | from group xlink:simpleLink |
| xlink:actuate | [0..1] | Anonymous | The 'actuate' attribute is used to communicate the desired timing of traversal from the starting resource to the ending resource; it's value should be treated as follows: onLoad - traverse to the ending resource immediately on loading the starting resource onRequest - traverse from the starting resource to the ending resource only on a post-loading event triggered for this purpose other - behavior is unconstrained; examine other markup in link for hints none - behavior is unconstrained | from group xlink:simpleLink |
| nilReason | [0..1] | gml:NilReasonType | from group gml:AssociationAttributeGroup | |
| gml:remoteSchema | [0..1] | xsd:anyURI | from group gml:AssociationAttributeGroup |
