[jsr-314-open] Cleaning up the composite PDL

The composite PDL currently has an exmaple component, which takes up a rather large amount of space, and, I feel, doesn't really give a lot of information for someone coming to the technology for the first time. At the same time, important information like the specialness of the values "action", "actionListener", "validator", and "valueChangeListener" are buried in the name attribute of the composite:attribute page. I think we might be better served by removing the example (or else, using a much smaller and simpler example), and including information like the special names in that freed space. What do you guys think? Am I off base? I've filed the following spec issue 572 to track this: https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=572 Jim
