   Parent element	tsd:elementInfo or tsd:attributeInfo
   Child elements	tsd:which, tsd:native, tsd:map
   Attributes	None

   Example

   The following example shows the use of the tsd:physical element in TSD:

   <tsd:physical>
     <tsd:native>
       <tsd:objectRef>
         <tsd:collectionRef>Customers</tsd:collectionRef>
         <tsd:accessPredicate operator = "=">
           <tsd:nodeRef>/Customer/CustomerNo</tsd:nodeRef>
         </tsd:accessPredicate>
       </tsd:objectRef>
     </tsd:native>
   </tsd:physical>
   

2. In the context of tsd:shadowXML:

   Purpose	This element controls the physical storage of the corresponding doctype.
   Parent element	tsd:shadowXML
   Child elements	tsd:map, tsd:structureIndex, tsd:compress
   Attributes	None

3. In the context of tsd:doctype:

   Purpose	This element controls the storage of the corresponding doctype. In this usage scenario it must not be specified when tsd:nonXML is used, because these elements are mutually exclusive.
