    static void validateDCL()
    {
        ContentVersion cv = new ContentVersion();
        cv.title = 'test content trigger';      
        cv.PathOnClient ='test';  
        Blob bodyBlob=Blob.valueOf('Unit Test ContentVersion Body');         
        cv.VersionData =bodyBlob;          
        insert cv; 
        
        ContentDocumentLink contentlink=new ContentDocumentLink();
