Question on ADQL-x regional expression

Hello Skynode developer,

I have some questions about ADQL-x regional expression.

In a draft of ADQL-v0.9, the following example is presented to express a circle region.

   <Region xmlns:q1="urn:nvo-region" xsi:type="q1:circleType" coord_system_id="">

<q1:Center ID="" coord_system_id="">

         <Pos3Vector xmlns="urn:nvo-coords"> 
            <Name>X Y Z</Name>
            <CoordValue> 
            <Value> 
               <double>1.2</double> 
               <double>2.4</double> 
               <double>3.6</double> 
            </Value>
            </CoordValue> 
         </Pos3Vector> 


      </q1:Center> 

      <q1:Radius>0.2</q1:Radius>

   </Region>

But, according to the STC region schema

   http://www.ivoa.net/xml/STC/STCregion/region-1.0.xsd the valid expression is like this:

   <Region xsi:type="q1:circleType" coord_system_id="FK5" unit="deg">

<q1:Center>34.2 -5.0</q1:Center>
<q1:Radius>0.0020</q1:Radius>

   </Region>

Our JVO skynode and skynode cliant follows the latter expression, while NVO skynodes follows the former expression. So we have problem to access to the NVO skynodes.

My questions are:

  Which expression is the standard ?
  Which expression is used for January ASS meeting demo ?   Which expression do Astro-Grid skynodes follow ?

Regards,
