System.Management.Automation.PagingParameters (class)

The System.Management.Automation.PagingParameters class seems to be related to using System.Management.Automation.CmdletBindingAttribute with the SupportsPaging attribute:
function xyx {

   [CmdletBinding(SupportsPaging = $true)]

    …
   $skip  = $PSCmdlet.PagingParameters.Skip
   $first = $PSCmdlet.PagingParameters.First
    …
     
}
