That sense of the term was actually co-opted from what people are talking about in this discussion, i.e., rdf, microdata, etc. They are related though, as using the correct HTML tags was meant to be a first step into adding a layer of meaning to web content that wasn't there before. But "the semantic web" includes a whole, whole lot more than just semantic markup. Hope that clarifies a bit!
