[Roni Even] This are partial examples from the clue data model document just to show the relevant part. They were not meant to be valid xml , I can add text to explain this

[Roni Even] OK

[Roni Even] I agree, it is also a passive language
Old text
"In multi-party communication scenarios using RTP Middleboxes, a lot of trust is placed on these middleboxes to preserve the sessions security"
New text
"In multi-party communication scenarios using RTP Middleboxes; these middleboxes are trusted to preserve the sessions security"

As for the "SHOULD maintain" it may depend on application policies (for example allowing users with different security levels into a multipoint conference)
