Additional attributes:
A tag identifies an SGML markup construct.
The utility of this element is almost
wholly constrained to books about SGML.
The tag element is sufficient for most XML constructs, which
are identical to the corresponding SGML constructs, it but does
not have any provisions for handling the special features of XML
markup. A future version of DocBook will address this issue,
probably by adding new Class
values.  In the 
meantime, you may get by by assigning a Role
attribute for XML.
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.
