The full set of possible values that may be assigned can be viewed by creating an instance of the CmdletBinding object:

PS> [CmdletBinding]::new()

PositionalBinding       : True
DefaultParameterSetName :
SupportsShouldProcess   : False
SupportsPaging          : False
SupportsTransactions    : False
ConfirmImpact           : Medium
HelpUri                 :
RemotingCapability      : PowerShell
TypeId                  : System.Management.Automation.CmdletBindingAttribute

For example, the output from the preceding command shows the existence of a PositionalBinding property. Setting this to false disables automatic position binding:

function Test-Binding {
    [CmdletBinding(PositionalBinding = $false)]
    param (
        $Parameter1
    )
}

When the preceding function is called, and a value for Parameter1 is given by position, an error will be thrown:

PS> Test-Binding 'value'
Test-Binding : A positional parameter cannot be found that accepts argument 'value'.
At line:1 char:1
+ test-binding 'value'
+ ~~~~~~~~~~~~~~~~~~~~
 + CategoryInfo : InvalidArgument: (:) [Test-Binding], ParameterBindingException
 + FullyQualifiedErrorId : PositionalParameterNotFound,Test-Binding

The most commonly used properties of CmdletBinding are SupportsShouldProcess and DefaultParameterSetName. DefaultParameterSetName will be explored in the next chapter.
