I cannot use user params this way, since I'm trying to pass some data to internal templates used to render a datatype (link tags within ezxml text).. they don't see any of these, afaik.
I'd like to have the ability to use that data to render links in some other way..
I've also tried to pass params to attribute_view_gui but it also doesn't work.
Which template variables are set for the link.tpl template? In ezxhtmlxmloutput.php handler, I can see only 'href', 'target', 'classification', 'title', and 'id' ... which are of no use so far :(
