Description
Apache SIS provides an XML.SCHEMAS property which can be set on Marshaller for controlling the namespace used in code list and units of measurement. But to be consistent, the namespace change should be apply on the whole XML document including the xmlns:gmd declarations in the root gmd:MD_Metadata element (or any other root).
Since SIS-479 changes the default value of xmlns:gmd, we need this mechanism for allowing users to keep the old namespace if they need too.
