I looked and the tcl tag is not used anywhere in OpenACS and
to be honest I think I am quite happy about that. I think
most html formatting tools will not look through <% tags
but they will definitely mess with stuff bound by <tcl>
I would be inclined to remove it.
And as Dave said, we would like to see less tcl (i.e. none)
in the .adp files so if there is something that is hard to
do with the current tag set we should add a tag to make it easy, not force designers to deal with tcl arcana.
I would argue for removing the tcl tag and not adding any of these interesting but I think ultimately troublesome tags
you are proposing.
