Extension_Information:
    Extended_Element_Name: Cross_Reference_Relevance
    Short_Name: crossrl
    Parent: Cross_Reference
    Type: text
    Domain: free text
    Optionality: Mandatory
    Repeatability: Not Repeatable
    Definition: The relevance for the cross reference citation
    Rationale: Since we will be filling our database with DGGS specific citations as well as outside references and our database disinguishes between them we need a free text field in all ciation areas (like supplemental information, source contribution) that can account for additional information known about a citation.

    Rationale: In order for our GERILA (Geologic and Earth Resource Information Library of Alaska) database to be able to distiguish which information (coordinate system, and resoulution values) is related to which layer or coverage we must specify the layer name here.
