While editing some form elements, I noticed a "Content Sandboxing" option. I looked at a Course Offering Information page, but don't see this element. What is it?

Update, I found references to a config variable, but they don't explain what it means: https://community.d2l.com/brightspace/kb/articles/4735-security-configuration-variables
