How to validate dependent parameters in PowerShell cmdlet

What's the best way to do PowerShell cmdlet validation on dependent
parameters? For example, in the sample cmdlet below I need to run
validation that Low is greater than High but that doesn't seem to be
possible with validation attributes.
[Cmdlet(VerbsCommon.Get, "FakeData")]
public class GetFakeData : PSCmdlet
{
[Parameter(Mandatory = true)]
[ValidateNotNullOrEmpty]
public int Low { get; set; }
[Parameter(Mandatory = true)]
[ValidateNotNullOrEmpty]
public int High { get; set; }
protected override void BeginProcessing()
{
if (Low >= High)
{
// Is there a better exception to throw here?
throw new CmdletInvocationException("Low must be less than
High");
}
base.BeginProcessing();
}
protected override void OnProcessRecord()
{
// Do stuff...
}
}
Is there is a better way to do this? The main thing I don't like about the
solution above is that I can't throw a ParameterBindingException like the
validation attributes would do since it's an internal class. I could throw
ArgumentException or PSArgumentException but those are really for Methods
not cmdlets.
