Description
A tag identifies an XML or
SGML markup construct. The utility of this element is
almost wholly constrained to books about markup.
Processing expectations
Formatted inline.
A tag generates all the necessary punctuation
before and after the construct it identifies. For example, it
generates both the leading ampersand and the trailing semicolon when
the class is
genentity.
