Our 7-year anniversary and another great round table discussion with a roomful of local and a handful of remote attendees. Lots of opinions and discussions about why or why not to include a <p> tag in a list or table cell, or to include a list in a <p> or other block elements. Discussed the differences between the various monospaced tagging options .. and many other DITA mark-up issues.
We used The DITA Style Guide, by Tony Self, as our guide as well as one source for a possible solution when you run into a DITA tagging problem.
