XForms Alert!

Hello all,

In 7.14.4.4 alert (Working Draft 20010828)
they never speak about commonUIChildren
But
in XForms Schema we can see

<xsd:element name="alert">
    <xsd:complexType mixed="false">
      <xsd:group ref="xform:commonUIChildren"/>
      <xsd:attribute name="id" type="xsd:ID" use="optional"/>
      <xsd:attributeGroup ref="xform:commonUIAttributes"/>
      <xsd:attributeGroup ref="xform:linkingAttributes"/>
    </xsd:complexType>
  </xsd:element>

Which document is true!
I think taht the Schema is wrong.
Please , give me your opinion.


Thanks!

Xavier
