Update 2025-09-14

New features:

• Add <dev:type> in <command:parameterValue> for Maml help generation. In order to be able to read the parameter type from the Maml reader.
• Assign alias values for parameter in MAML help generation
• Render accepted values in generating Maml help.

Bug fixes:

• Don't render <command:parameterValue> if the parameter is SwitchParameter. This fixes a problem that the syntax parameter have been outputed as [-Flag <SwitchParamerter>] instead of [-Flag]
• Fix: required attribute of <command:parameterValue> should be true
• Fix: a problem in which HasCmdletBinding of CommandHelp and HasCmdletBinding of each SytanxItem were out of sync when loading Maml Help. This will cause [<CommonParameters>] to be missing from the end of the syntax when exported.
