It also should be taken into account the full type hierarchy matters if data is stored by fragments and the XPath property is being used as a
model revision identifier as well. If parent model is changed while child model remains the same (revision) the child data fragment  will also
differ depending on fragment became
dependent on parent (revision) context. It makes a requirement the fully qualified type definitions should be stored with data fragments (XPath)
for all the nodes

/* clear parent context difference */
/org:onap:sample:parentType(2020-01-01)[@attr1='value1']/org:onap:sample:childType(2020-02-02)[@attr2='value2']
/org:onap:sample:parentType(2020-02-02)[@attr1='value1']/org:onap:sample:childType(2020-02-02)[@attr2='value2']

/* unclear parent context (if only current node type is stored in database) */
