<para>The <ulink url="mailto:docbook-tc@oasis-open.org">DocBook

<para>There’s an historical reason for the large number of unique
names: customizers might very well want to adjust the content models
of info elements at different levels. For example, a copyright
-statement might be required at the book level, or an an author
+statement might be required at the book level, or an author
forbidden at the sub-section level. In DTDs, there’s only one content
model allowed per element name, so in order to support independent
customization, each info element must have a different name.</para>

<para>DocBook V5.0 adds a few simple data types. For example, the
