Yes, basically you're saying that since looping tags are parsed ahead of
time I can use them in spite of them being restricted (or not explicitly
Please correct me if I'm worong here, but I don't think this will work
for the following reason...
The main problem is that the looping tags can't be reparsed (with
iterpolate=1) so there's no way to get them to parse the area and page
tags inside the comment. I could have just as easily done this (and I
tried it) but it has the same problem:
[restrict enable="area page"][item-field comment][/restrict]
hence the reason I have to use the field tag instead of the PREFIX-field
tag, or any looping tag for that matter.
I can live with having to enable the field tag if I have to but it's a
loose end I'd like to clean up if I can.
It also seems to me to be a rather serious flaw of the restrict tag in
that the primary usage of the tag would seem to me to allow for the
restricted parsing of tags in included text where you don't know what
might be inside it, hence it seems like the real legitimate usage of the
tag would require inclusion of some external source without having to
compromise the inclusion tag itself. And of course, reparsing of the
inclusion tag output is also necessary for this which eliminates a lot
of possible inclusion mechanisms.
