I am currently encountering errors related to the context of an extension.

The extension is located within the Human.family element, and error indicates that the extension is expected to be inside the Human.family element. Am I understanding this correctly, or could there be a misunderstanding?

[ERROR] Extension used outside of appropriate contexts. Expected context to be one of: {ELEMENT,HumanName.family} (at Bundle.entry[1].resource[0].name[0].family[0].extension[0]

The Element:

            <name>
               <use value="official"/>
               <family value="LastnameExample">
                  <extension url="http://hl7.org/fhir/StructureDefinition/humanname-own-name">
                     <valueString value="LastnameExample"/>
                  </extension>
               </family>
               <given value="FirstNameExample"/>
            </name>
