Thanks Michael.  I just got in to work today and was about to make a special "INSPIRE" copy of the schemas for you when I read your email.

Cheers,
Ollie

Hi again,

as a quick fix, I have now created a (temporal) copy of the v3.0 RC2
schemas on http://inspire-twg.jrc.ec.europa.eu/annexII+III/schemas/ and
have modified all the internal references to point to this copy.

We will publish a fix of the INSPIRE schemas that refers to this
temporal copy rather than the original at
https://www.seegrid.csiro.au/subversion/GeoSciML/tags/3.0.0_rc2/schemas/

So there's no urgent need from our side to fix the RC2 schemas.

Cheers,
Michael
