I believe that's correct.

Are you sure?  My understanding is that:

  <xs:complexType/>

is short for

  <xs:complexType>
    <xs:complexContent>
      <xs:restriction base="xs:anyType">
      </xs:restriction>
    </xs:complexContent>
  </xs:complexType>

which allows neither attributes, child elements not child text nodes, and
thus that

  <xs:complexType mixed="true"/>

allows just child text nodes and hence is equivalent to

  <text/>

in RELAX NG.  I may be wrong -- I often find I misunderstand XSD -- but both
MSXML and XSV seem to agree with me (the version of MSV I tried doesn't
though).

Only if somebody reports them.
