In theory ISO provides extensibility options via profiling which allows
information communities to extend/constrain the 19115 according to their
requirements.  Examples of profiles include the WMO Core Metadata Profile,
and the North American Profile.  In general these profiles do not provide
new elements but lay out specific rules around code lists, vocabularies and
required fields around the existing ISO element set.

In the dataset attribute case 19115 allows specification of attributes by
reference to a ISO 19110 definition via URL. I suppose we could simply
hack/extend GeoNode's ISO output in practice with new elements but this would
hurt interoperability and widespread adoption given it's a local/specific
changeset.

Hope this helps.
