Object Relationship Checking
ComplexObservation & ConversionTable [WDTS-536]A three-tier referential relationship check is now implemented:

- From wdtf:ConversionTable and wdtf:ComplexObservation to wdtf:ComplexPropertyDefinition; and
- wdtf:DurationGroup to wdtf:ComplexPropertyDefinition.
The value of attributes xlink:href and xlink:arcrole, under wdtf:BorePipeSamplingInterval/sa:relatedSamplingFeature, are checked in three parts:
- Existence of a wdtf:SamplingGroup referenced by xlink:href when associated xlink:arcrole indicates it as a 'parent'.
- Existence of a wdtf:Bore referenced by xlink:href when associated xlink:arcrole indicates it as an 'enclosure'.
- For the two mandatory instances of sa:relatedSamplingFeature, one must be a 'parent' indicated by associated xlink:arcrole, while the other must be indicated as an 'enclosure'.
The attribute value 'xsi:nil', under wdtf:location, determines if the child elements GeographicalDescription and Point can be either both be omitted or whether one of them should be present:
- If set to xsi:nil=false, either GeographicalDescription OR Point will be present.
- If set to xsi:nil=true, both GeographicalDescription and Point can be omitted.
