[GeoSciML] metadata schema (Borehole)

[Boisvert, Eric]

I ran into a small problem while generating Borehole schema.
This package has a dependency to ISO/CD 19115-3 Metadata, (for cit:CI_Responsibility_PropertyType) and there are no schema location.  I found an xsd in a GitHub repo (it's the xsd Steve is working on) and used that location

https://raw.githubusercontent.com/ISO-TC211/XML/master/ISO19115-3/lan/1.0/2014-07-11/language.xsd

is everyone ok with this ?
