Character level elements are used to specify either the structural
meaning or the physical appearence of marked text without causing a
paragraph break. Like most other elements, character level elements
include both start and end tags. Only the characters between the tags
are effected. For example:
This is <EM>emphasized</EM> text.
Highlighting elements are allowed within the content of other
highlighting elements, but implementations are not required to render
these nested highlighting elements distinctly from non-nested elements.
For example, implementations may render the following two cases
plain <B>bold <I>italic</I></B>
plain <B>bold </B><I>italic</I>
Some character highlighting styles are more explicit than others
about how they should be physically represented. Designate the
information type rather than the character format wherever possible,
unless for example, it is necessary to refer to the text as in "The
italic parts are mandatory".

- This a space separated list of SGML NAME tokens and is
used to subclass tag names. By convention, the class names are
interpreted hierarchically, with the most general class on the left and
the most specific on the right, where classes are separated by a
period. The CLASS attribute is most commonly used to attach a different
style to some element, but it is recommended that where practical class
names should be picked on the basis of the element's semantics, as this
will permit other uses, such as restricting search through documents by
matching on element class names. The conventions for choosing class
names are outside the scope of this specification.
