Editing .ymt (PSO/RSC) files using an assembly.xml in a .oiv... Fatal Error

[LowSpecRider]

Hello there!
Guys, I'm trying to modify carcols.ymt using a .oiv installer (to create a custom pattern for non-els police car), but every time that I run it, it just return a fatal error.

Do you have any idea what I did wrong?

This is my test code:

<?xml version="1.0" encoding="UTF-8"?>
<package version="2.2" id="{6D501E5D-DD68-42CB-ACA4-A920DFC905E3}" target="Five">

		<Item>This_Is_A_Test_Line_O:</Item>
	</add>
     </pso>
	 </archive>
  </content>
</package>

The installation log is presented here:

YMT files are encrypted files, you can't modify them like you can with meta files. That's why if you right-click carcols.ymt in OpenIV, it has an "Export to META/XML" option... doing the same thing on a carcols.meta file doesn't show that option.
