I would suggest that you instead allow regular <a> elements in the text. If the URL must be processed somehow (e.g. expanded with a some special prefix, URL rewritten, etc. your <article:display> can simply parse out the <a> elements, process them and add the result to the output stream. This way the author can use an HTML element she is familiar with, no need to learn a new one. If the processing is complex, and if you want to invoke it in other places using the <a:link> action, put it in a separate class that you can use from both the <a:link> and the <article:display> tag handlers. Or did I miss something?
