I remember dreamweaver, and I have the mental scars to show from using it. However, dreamweaver came about in the time of table-based layout and refused to adapt when the market consensus moved to div- (and later semantic element-) based layouts. There's no reason that I can see, that you wouldn't be able to name the elements in a document (or ML could be perhaps used to auto-derive names), and beyond that, my understanding is that semantic markup (at least in terms of class/ID names) hasn't proven to be all that important since the advent of the API. Perhaps it's just not been done well enough so far to justify moving over from HTML/CSS, but you'd expect people to be jumping to solve their own issues. I for one find CSS/HTML tweaking to be pretty monotonous when I'm just trying to get to an end result.
