new data model does not work with all acl conditions

the new datamodel schema mcrcommon-datamodel.xsd can't work with all conditions of ACLs they are possible in MyCoRe.

Workaround is

<xs:element name="servacl">
<xs:complexType>
<xs:sequence>
<!--
<xs:element maxOccurs="unbounded" ref="condition" /> <xs:element maxOccurs="unbounded" ref="condition" />
-->
<xs:any processContents="skip"/>
</xs:sequence>

But this is not the solution!
