We didn't have any XSD gurus in the mzML group or they didn't chime in so  
the
uniqueness of nativeID is not XSD-derived, it's in the specification docs  
and the
semantic validators enforce it (actually they are much more than just  
unique, their
format is strictly defined depending on the source file). I presume this is  
the
related XSD uniqueness code, what does it mean in plain english? :)
   <xsd:element name="SpectrumIdentificationList"
type="psi-pi:PSI-PI.analysis.search.SpectrumIdentificationListType"  
abstract="false"
substitutionGroup="psi-pi:AnalysisResultList">
     <xsd:unique name="PK_COMPOSITE_SpecRef">
        <xsd:selector xpath="./*"/>
         <xsd:field xpath="@spectrumID"/>
         <xsd:field xpath="@SpectraData_ref"/>
      </xsd:unique>
   </xsd:element>

I don't understand the hesitation to use nativeID which already has the "if  
mzML it
means this, if mzData it means this, if mzXML it means this, if MGF it  
means this,
etc." logic defined. That way implementers can use the same nativeID  
parsing code for
both standards.
