This element is used exactly in the same way as the “Count” element except that the “value” property takes a space separated pair of integers. The next example shows how to
specify an array index range:
swe:Count definition
= http:www.opengis.netdefpropertyOGC0ArrayIndex
swe:label Index Range
swe:label swe:value
0 9999 swe:value
swe:Count
The pair of values can be omitted like with any other data component in the case where it is provided in a separate data stream.
8.1.11 QuantityRange Element
The “QuantityRange” element is the XML schema implementation of the “QuantityRange” UML class defined in clause 7.2.13. The schema snippet for this
element and its corresponding complex type is shown below:
element name
= QuantityRange
substitutionGroup =
swe:AbstractSimpleComponent type
= swe:QuantityRangeType
complexType name
= QuantityRangeType

base =
swe:AbstractSimpleComponentType sequence

This element is used exactly in the same way as the “Quantity” element except that the “value” property takes a space separated pair of double values. The next example shows
how to express the operational range of a thermometer in Kelvins:
swe:QuantityRange definition
= http:mmisw.orgontmmideviceOperationalRange
swe:label Operational Range
swe:label swe:description
Operational range of the cryogenic thermometer swe:description

8.1.12 TimeRange Element
The “TimeRange” element is the XML schema implementation of the “TimeRange” UML class defined in clause 7.2.14. The schema snippet for this element and its
corresponding complex type is shown below:
element name
= TimeRange
substitutionGroup =
swe:AbstractSimpleComponent type
= swe:TimeRangeType
complexType name

This element is used exactly in the same way as the “Time” element except that the “value” property takes a space separated pair of time positions. The next example shows
how to express a time period with such a component:
swe:TimeRange definition
= http:www.opengis.netdefpropertyEO0SurveyPeriod
swe:label Survey Period

The pair of time positions can be omitted like with any other data component in the case where it is provided in a separate data stream.
8.1.13 Quality Element Group
The “Quality” group is the XML schema implementation of the “Quality” Union UML classifier defined in clause 7.2.15. The schema snippet for this XML schema group is
shown below:
group name
= Quality
choice element
ref =
swe:Quantity element
ref =
swe:QuantityRange element
