Does IntellJ support the checking for "keyref" definition?

Why it seems does not work at all?

<xs:key name="supported-platforms-name-unique">
<xs:selector xpath=".//supported-platforms/platform"/>
<xs:field xpath="."/>
</xs:key>

<xs:keyref name="platforms-name-ref"
refer="supported-platforms-name-unique">
<xs:selector xpath=".//schema-info"/>
<xs:field xpath="platform-name"/>
</xs:keyref>

Thanks!
