Variables in the DSC resource?

DSC

Hello, I’ve been banging my head on this stuff for a while, so lets imagine I have a resource:

Configuration WebProxy
{     
Param (
    [Parameter(Mandatory=$true)][string] $url
    )
Import-DscResource -Module nx
Node webproxy {  
        nxFile ProxyConf 
        {
            SourcePath = "$url_variable_goes_here"
            DestinationPath = '/etc/nginx/sites-available/proxy'
        }  
    }
}

So, I figured I could use configdata, but that’s not convinient, I’d like to be able to pass value from pipeline at mof compile time, is that possible?
