The stylesheet is incomplete: it forgets the attribute 'memberTypes' for which doubtless it should also transform QNames without namespace into QNames with the new target namespace. The following template rule would do the job.

With kind regards -

  <xsl:template match="@memberTypes">
    <xsl:variable name="context" select=".."/>
    <xsl:variable name="values" as="xs:string+">
       <xsl:for-each select="tokenize(., '\s+')">
          <xsl:variable name="oldValue" 
                        select="resolve-QName(., $context)" 
                        as="xs:QName"/>
          <xsl:sequence 
             select="if (namespace-uri-from-QName($oldValue) eq '') 
                then concat($prefixForTargetNamespace, ':', 
                            local-name-from-QName($oldValue))
                else string(.)"/>
       </xsl:for-each>
    </xsl:variable>
    <xsl:attribute name="{name()}" select="string-join($values, ' ')"/> 
  </xsl:template>
