yes, that assumes I have some way of working out what "italic" means, as now

so can we say, 

  * @style and @rendition are from a formal descriptive  language, and are cumulative
  * @rend is an alternate to @style/@rendition. if both exist, a processor can follow which it likes, depending on what its trying to do
  * if there is nothing on the element at all, you can look up tagsDecl/@render to see what the thing looked like


?

or are @style/@rendition building on tagsDecl/@render?
