        <ParameterBinding Name="Today" Location="CAMLVariable" DefaultValue="CurrentDate"/>
    </ParameterBindings> ]]> </ dvwp:ParamBindings >

We can be found in a screening when there are two sharepoint provide their own attributes and UserID Today, here we can add your own

         < ParameterBinding  Name ="_name"  Location ="Postback;QueryString(name)"  DefaultValue ="" />
         < ParameterBinding  Name ="_email"  Location ="Postback;QueryString(email)"  DefaultValue ="" />

At this time, we can use custom parameters through the screening dataview.
