.SYNOPSIS

    PowerShellXML Language Definition

.DESCRIPTION

    Allows PipeScript to generate PS1XML.

    Multiline comments blocks like this ```<!--{}-->``` will be treated as blocks of PipeScript.

.EXAMPLE

    $typesFile, $typeDefinition, $scriptMethod = Invoke-PipeScript {

        types.ps1xml template '

        <Types>

            <!--{param([Alias("TypeDefinition")]$TypeDefinitions) $TypeDefinitions }-->

        </Types>

        '

        typeDefinition.ps1xml template '

        <Type>

            <!--{param([Alias("PSTypeName")]$TypeName) "<Name>$($typename)</Name>" }-->

            <!--{param([Alias("PSMembers","Member")]$Members) "<Members>$($members)</Members>" }-->

        </Type>

        '

        scriptMethod.ps1xml template '

        <ScriptMethod>

            <!--{param([Alias("Name")]$MethodName) "<Name>$($MethodName)</Name>" }-->

            <!--{param([ScriptBlock]$MethodDefinition) "<Script>$([Security.SecurityElement]::Escape("$MethodDefinition"))</Script>" }-->

        </ScriptMethod>

        '

    }

    $typesFile.Save("Test.types.ps1xml",

        $typeDefinition.Evaluate(@{

            TypeName='foobar'
