I really don't understand caller.attributes.variable. Maybe somebody could
explain why you would ever do this? Or if it would really work. And on this
topic, is it possible to assign any name for a scope of a variable? Like
myvariables.variable? Cause it seems like this is what you would be doing by
using caller.attribute.variable. caller would be the scope, attribute would
be your custom named scope, and variable would be the variable name. Am I
just confused here or what?
Thanks,
Rick

It would really depend on what you wanted the tag to do.
In your case none of them really apply. As your already using it to set a
persistant variable.
If you were using the tag to update an attribute. scoped variable already in
place on the calling template/tag it would be
caller.attributes.somevar
If you were using it to update a request. scoped variable (variable that's
alive for the duration of the page request) no caller. is needed as request.
scoped variable will cross tag boundaries so it would just be
request.somevar.
If the tag is just setting a local variable used by the calling template
then its just caller.somevar.
Hope this helps
