Anonymous group?

Is it alright to have a group element with no name in a Schema? 

E.g.

<complexType name="data">
 <sequence>
  <element name="number" type="integer"/>
   <group minOccurs="0">
    <sequence>
      <element name="anotherNumber" type="integer"/>
    ...
   </group>
...

The name and ref attributes look optional in [1] but XSV gives 2
errors,  Invalid: group with no name or ref and Invalid: internal group
must have ref.

Thanks,

Jasmin Wason
