Example

Let us say that we want to configure a few validations based on extensions for a file <property> in the destination resource. The requirements are as follows,

    
        copy
        
            
        
    
    
          
png: 3 files each with size 500 to 1000 bytes
xml: 2 files each with size 1000 to 1500 bytes

Use the above details and write the extension as shown here.

    
        copy
        
            
        
    
    
         
<property name="tourist_spots" type="file" length="5">
    <file-meta overall-size="6000" import-url="false" continue-on-error="true">
        <extension name="png" size="500,1000" length="3"/>
        <extension name="jpg" length="2"/> 
    </file-meta>
</property>
