The spec doesn't answer that question. I am inclined to say no, because, although this simple example is straightforward (perhaps) it could be a syntactical nightmare when you tag portions of the string and have to include parenthesis delimiters. And of course the hypenation would make it more complicated. Other thoughts on this? --Ray
