om:observedProperty
Link to a description of the property or phenomenon whose value is being described or estimated through observation for example "wavelength", "grass-species", "power", "intensity in the waveband xy", etc. It is this feature-property that provides the (semantic) type of the observation. Note that the description of the phenomenon may be quite specific and constrained. In general the precise details of the constraints describing the observe properties require attention to the procedure used in making the observation: e.g. an optical sensor typically has a wavelength-dependent response. This property may be provided for client convenience, to allow comparison between and aggregation of observations of the same property made using different procedures.

Content
- Choice [1..1]
- swe:Phenomenon [0..1] Use the generic gml:DefinitionType for basic Phenomenon definitions, gml:description may be used for a more extensive description of the semantics, with a link to a definitive version (if available). gml:name should be used for the "short name" or label.
- swe:ConstrainedPhenomenon [0..1] Description of a scalar Phenomenon defined by adding constraints to a property previously defined elsewhere.
- swe:CompositePhenomenon [0..1] A Composite Phenomenon Definition is composed from arbitrary base Phenomena.
- swe:PhenomenonSeries [0..1] A Series is derived from a common basePhenomenon (e.g. Chemical Concentration) with one or more constraint lists (e.g. Chemical Species).
