2.8 Tagging frames

Collecting tag data from frames requires special consideration. It is not normally necessary to send a tag from a frame, but in some cases content in the frame requires tags.

Example: Tracking product reviews submitted or viewed within a child frame. If for technical reasons the Page View tag for the page cannot be sent from the parent document, the Page View tag can be sent from one of the child frames. As each new frame is a new document with a new variable scope, care must be taken to implement tags in child frames correctly.
