Thank you for stating your agreement, David. To make sure I understand 
and for the record: you agree with the schema change Jirka made, see also
http://lists.w3.org/Archives/Public/public-multilingualweb-lt-commits/2013May/0044.html
[foreign
elements can be used only inside its:rules. Foreign attributes can be
used on any element defined in ITS.]

?

Wrt to the spec change: having the text in prose description for all 
elements doesn't sound feasible. How about adding what you agreed to
"Foreign elements can be used only inside its:rules. Foreign attributes 
can be
used on any element defined in ITS."

To
http://www.w3.org/International/multilingualweb/lt/drafts/its20/its20.html#its-schemas

?

Best,

Felix
