Not a lot of explanation needed. These are all XHTML compliant, some include self closing tags and do not offer the option to avoid this, so some work may be necessary. In fact, there will probably be a lot of disagreement over how to handle a few things, and my feelings won't be hurt. Take this as a suggestion, and perhaps overkill. I actually prefer to just use the generic "insert open/close tag" these days, but agree that there are times that typing a tag and hitting tab would be convenient.
