thank you, Gustaf. It is into oacs-5-2 now 😊
One more stuff i needed to do to get oacsFS plugin working is about a type error in xowiki/www/xinha/file-selector.tcl file
In lines 121 and 130 i changed package_id switch value in proc fs::add_file from
fs::add_file \
...
-package_id $package_id
to
fs::add_file \
...
-package_id $fs_package_id
