LibreOffice uses this structure in the schema:

<rng:define name="common-value-and-type-attlist">
  <rng:choice>
    <rng:group>
      ...
    </rng:group>
    ...
    <rng:group>
      <rng:attribute name="office:value-type">
        <rng:choice>
          <rng:value>string</rng:value>
          <rng:value>error</rng:value>
        </rng:choice>
      </rng:attribute>
      <rng:optional>
        <rng:attribute name="office:string-value">
          <rng:ref name="string"/>
        </rng:attribute>
      </rng:optional>
    </rng:group>
  </rng:choice>
</rng:define>

I think, that could be divided into two groups:
<rng:define name="common-value-and-type-attlist">
  <rng:choice>
    <rng:group>
      ...
    </rng:group>
    ...
    <rng:group>
      <rng:attribute name="office:value-type">
          <rng:value>error</rng:value>
      </rng:attribute>
      <rng:optional>
        <rng:attribute name="office:string-value">
          <rng:ref name="string"/>
        </rng:attribute>
      </rng:optional>
    </rng:group>
    <rng:group>
      <rng:attribute name="office:value-type">
          <rng:value>string</rng:value>
      </rng:attribute>
      <rng:optional>
        <rng:attribute name="office:string-value">
          <rng:ref name="string"/>
        </rng:attribute>
      </rng:optional>
    </rng:group>
  </rng:choice>
</rng:define>

So there is no attribute "office:error" but "error" is a value of 
attribute "office:value-type".

Kind regards
