> In a metadata XML document, an element may be replaced by a reference to
> another element. [Example derived from
> catalog.data.gov|https://catalog.data.gov/harvest/object/d2901928-f55b-4ef3-88e9-9de7d3e30554]
> (search {{Level_2}} in that document):
> {code:xml}
> <gmd:processStep>
> <gmi:LE_ProcessStep>
> <gmd:source xlink:href="#Level_2"/>
> </gmi:LE_ProcessStep>
> </gmd:processStep>
> <gmd:source>
> <gmd:LI_Source id="Level_2">
> <gmd:description>
> <gco:CharacterString>Source Contribution: The Level 2 data are used
> in processing Level 3 data.</gco:CharacterString>

> Support of such reference has been implemented in SIS-173, but only in the
> cases where the content is defined before {{xlink:href}}. In above example,
> we have the opposite order. Such forward references should be implemented in
> SIS. One possible approach may be to to store the parent object and the
> property name in a {{java.util.Map}} until the definition is found, in which
> case we can use {{AbstractMetadata.asMap()}} for setting the final value.
