ISO/TC 211 Geographic Information/Geomatics [1] has published the
standard ISO 19139 Geographic information -- Metadata -- XML schema
implementation [2] which informatively references the XML schema [3]
which in turn calls an OGC schema [4] for the W3C xlink 1999 namespace
[5] because there was no XML schema published for the 1999 version of
xlink.

I've not checked the differences between the two schemata which refer to
the same namespace[5], but, you may wish to liaise with OGC or ISO to
update this link in step with your developments in order to improve
adoption of your new work. If not you may find that any
incompatibilities between the informative OGC schema and your
informative schema may cause delays to the adoption of your schema.
