VOEvent Update

[Pierre Le Sidaner]

My proposition is not to modify these two main items but the fields under
for example for time having
      <xs:element name="ISOTime" type="xs:string" minOccurs="0" 
maxOccurs="1"/>
       <xs:element name="TimeOffset" type="xs:float" minOccurs="0" 
maxOccurs="1"/>
       <xs:element name="TimeScale" type="xs:string" minOccurs="0" 
maxOccurs="1"/>
      <xs:element name="TimeOrigin" type="xs:string" minOccurs="0" 
maxOccurs="1"/>

On the other hand, in planetary science we point out that the wherewhen part could not allow description of planetary objects and even may be a problem for satellite position and time description. Even spherical coordinate could be a problem as all coordinate share the same unit.
