If you can file a GitHub issue<br>
(<a href="https://github.com/geopython/pycsw/issues/new" rel="noreferrer" target="_blank">https://github.com/geopython/pycsw/issues/new</a>), that would be great.<br>

<br>
pycsw generally leaves that up to the metadata provider. For ISO, generally:<br>
<br>
19139 (data): <a href="http://www.isotc211.org/2005/gmd/gmd.xsd" rel="noreferrer" target="_blank">http://www.isotc211.org/2005/gmd/gmd.xsd</a><br>
19119 (services): <a href="http://schemas.opengis.net/iso/19139/20060504/srv/srv.xsd" rel="noreferrer" target="_blank">http://schemas.opengis.net/iso/19139/20060504/srv/srv.xsd</a><br>
<br>
Note that the CSW ISO Application Profile provides<br>
<a href="http://schemas.opengis.net/csw/2.0.2/profiles/apiso/1.0.0/apiso.xsd" rel="noreferrer" target="_blank">http://schemas.opengis.net/csw/2.0.2/profiles/apiso/1.0.0/apiso.xsd</a> as<br>
a convenience to support both data and services.<br>
<br>
Having said this, when I make some changes (invalid ISO dates,<br>
ordering of some elements, invalid xs:ID values), your metadata<br>
document in your example URL validates with no problem against<br>
<a href="http://schemas.opengis.net/csw/2.0.2/profiles/apiso/1.0.0/apiso.xsd" rel="noreferrer" target="_blank">http://schemas.opengis.net/csw/2.0.2/profiles/apiso/1.0.0/apiso.xsd</a><br>
<br>
Hope this helps.<br>
