ows:PositionType

Position instances hold the coordinates of a position in a coordinate reference system (CRS) referenced by the related "crs" attribute or elsewhere. For an angular coordinate axis that is physically continuous for multiple revolutions, but whose recorded values can be discontinuous, special conditions apply when the bounding box is continuous across the value discontinuity:
a)  If the bounding box is continuous clear around this angular axis, then ordinate values of minus and plus infinity shall be used.
b)  If the bounding box is continuous across the value discontinuity but is not continuous clear around this angular axis, then some non-normal value can be used if specified for a specific OWS use of the BoundingBoxType. For more information, see Subclauses 10.2.5 and C.13. 

This type is adapted from DirectPositionType and doubleList of GML 3.1. The adaptations include omission of all the attributes, since the needed information is included in the BoundingBoxType.
