Is this actually a legal XML Schema definition?

<xs:complexType name="FilterDevicePreset">
  <xs:all>
   <xs:element name="DeviceSlot" minOccurs="0" type="AudioPluginDevice"/>
   <xs:element name="DeviceSlot" minOccurs="0" type="BusCompressorDevice"/>
   <xs:element name="DeviceSlot" minOccurs="0" type="CabinetSimulatorDevice"/>
   ...
  </xs:all>
  <xs:attribute name="doc_version" use="required" type="xs:int" fixed="5"/>
  <xs:attribute name="type" use="optional" type="xs:string"/>
</xs:complexType>

I would guess it violates Validation Rule: QName resolution (Instance)

A pair of a local name and a namespace name (or absent) resolve to a schema component of a specified kind in the context of validation by appeal to the appropriate property of the schema being used for the assessment. Each such property indexes components by name.

Given the pair (no namespace, DeviceSlot) within the context of FilterDevicePreset, one would not be able to resolve to a single schema component.

Is this actually a legal XML Schema definition?

It seems that no. Apache xmlbeans show errors on this scheme. (I tried it after scalaxb)
