Parameter entities are used to simplify the DTD (reduce duplication)
and to allow the DTD to be customized by wrapper DTDs.  Parameter
entities beginning with "additional" are meant to allow easy extension
by wrapper DTDs.

<!-- Attributes
================================================================== -->

<!-- Boolean: no if zero(s), yes if any other value. -->
<!ENTITY % yesorno "NMTOKEN">

<!-- Emphasize that the attribute value must be a number. -->
<!ENTITY % number  "NMTOKEN">

<!-- A number which may be immediately followed by a unit. -->

<!--
Attributes shared by all elements in this DTD:

- `id` is a unique identifier, typically assigned by the system.
- `name` is an identifier assigned in the markup.
- `dupname` is the same as `name`, used when it's a duplicate.
- `source` is the name of the source of this document or fragment.
- `class` is used to transmit individuality information forward.

Inline elements occur within the text contents of body elements. Some
nesting of inline elements is allowed by these definitions, with the
following caveats:

- An inline element may not contain a nested element of the same type
  (e.g. <strong> may not contain another <strong>).
- Nested inline elements may or may not be supported by individual
  applications using this DTD.
- The inline elements <footnote_reference>, <citation_reference>,
  <literal>, and <image> do not support nesting.
