string array in Windows policy registry value

Hello,
 
Recently LibreOffice had the ability to read settings from the Windows registry as explained here: 
https://wiki.documentfoundation.org/ReleaseNotes/4.2#Windows_Registry_changes
 
This is fine for settings that can be set with one string. 
 
There are, however, settings that require multiple string values, such as: 
org.openoffice.Office.Common\Security\Scripting\SecureURL, which contain multiple values in <it> 
tags.
 
It there an undocumented delimiter that can be used in the registry Value that LibreOffice can use 
to split the string into multiple values? As this would be helpful in allowing Windows Systems 
Administrators to set Trusted File Locations via Group Policy.
 
This thread here talks about the issue in more detail:
