Schema Editor error validating <xs:attribute ref="xm

Hello all :wink:

I’m using Tamino 4.4.1 and i’m trying to define a schema. This schema (.xsd) is validated by XMLSpy, but when I try to define it in Tamino, a validation error occurs. The tag that causes the error is :

<xs:attribute ref="xml:lang"/>

… Cannot resolve the name ‘xml:lang’ to a(n) ‘attribute declaration’ component.

I’ve included the “xml” namespace, althougt in XMLSpy is not necessary:

<xs:schema xmlns="urn:hl7-org:v3" xmlns:xml="" xmlns:xs="" targetNamespace="urn:hl7-org:v3" elementFormDefault="qualified">
	<xs:import namespace="" schemaLocation=""/>

…but the same error occurs. Any idea?

Thanks in advance.
