Subject: Selective element based on attribute



Hi  there, 

How can I define an xsd for the following scenario? 

<parenttag attr="add | del | chg"> 
     <childtag1>chidvalue1</childtag1> 
     <childtag2>chidvalue2</childtag2> 
     <childtag3>chidvalue3</childtag3> 
</parenttag> 

Is it possible to create an xsd where childtag3 will have a value null if
the parenttag  attr equals add else a nonnull-String when the parenttag attr
is del/chg? 

Thanks 
Muthu
