Problem found (after long time of investigating). Some behavior of compiler was changes and property wasn't evaluated properly. This is a reason why RSS and XML were mixed.
My decision is remove RSS. It uses same clip definition, same highlighting as XML. I will add RSS extensions (RSS RSD) as default to XML. -- <https://forum.pspad.com/read.php?2,77874,77949> PSPad freeware editor https://www.pspad.com
