Vulnerability discussion

This policy setting allows you to manage dynamic binary and script behaviors of components that encapsulate specific functionality for HTML elements, to which they were attached. If you enable this policy setting, binary and script behaviors are available. If you select "Administrator approved" in the drop-down box, only the behaviors listed in the Admin-approved Behaviors under Binary Behaviors Security Restriction policy are available. If you disable this policy setting, binary and script behaviors are not available unless applications have implemented a custom security manager. If you do not configure this policy setting, binary and script behaviors are available.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
