Infer XSD from XML

<#
.SYNOPSIS
        Infers an xml schema from an xml file
.PARAMETER XMLPath
        Specifies the filename or FileInfo object representing the source xml file, for now relative paths will produce an error. Get-Item or Get-ChildItem provide a good workaround.
.PARAMETER XSDPath
        Specifies the full filename for the output xml schema file.
.EXAMPLE
        PS > Infer-XSD -XMLPath c:\menu.xml -XSDPath c:\menu.xsd
