Yes, but that fact in itself doesn't exclude it from being a formatting
language. The term "markup" just means that it marks text. It doesn't say
anything about the purpose of the markings.

In fact, there are several constructs in HTML that have exclusively to do
with formatting, though almost all of them are deprecated in HTML 4.0. Since
HTML 3.2 and HTML 4.0 Transitional include a number of formatting
mechanisms, it is not entirely inaccurate to call HTML a formatting
language. Nor does it tell the whole story.

At its core, HTML is a logical markup language, meaning that it includes
markup that attempts to qualitatively describe content, so that a user agent
can interpret it appropriately.

No. HTML 2.0, 3.2, and 4.0 are examples of SGML applications. XML is a
*derivative* of SGML. For the most part, it can be considered a subset of
SGML.
