That's not a correct fix. The correct fix is to add a declaration for the
'ifc' prefix:

<uos id="uos_1" description="" configuration="i-ifc2x3" edo=""
  xmlns="http://www.iai-tech.org/ifcXML/IFC2x3/FINAL"
  xmlns:ifc="http://www.iai-tech.org/ifcXML/IFC2x3/FINAL"
  xmlns:ex="urn:iso.org:standard:10303:part(28):version(2):xmlschema:common"
  xsi:schemaLocation="http://www.iai-tech.org/ifcXML/IFC2x3/FINAL IFC2X3.xsd">

This prefix is used in a fixed attribute value (of QName type) in IFC2X3.xsd,
IfcUnitAssignment type, inside the Units element, attribute name 'ex:itemType'.

With the above change the XML file validates without any errors.
