Reference pages (RefEntry
s) are usually identified
by a short, succinct topic name, such as the name of a function
or command. The RefName
(or one of the
RefName
s, in the case of a reference page that has
several) is generally used as the topic name. When none of the
RefName
s is appropriate, RefDescriptor
is used to specify the topic name.
RefDescriptor
is unnecessary when an appropriate
RefName
can be selected automatically. At least one
RefName
is required, so RefDescriptor
cannot
be used in place of a name, only in addition to it.
May be formatted inline or as a displayed block, depending on context.
Formatting reference pages may require a fairly sophisticated
processing system. Much of the meta-information about a
reference page (its name, type, purpose, title, and
classification) is stored in wrappers near the beginning of
the RefEntry
.
Common presentational features, such as titles and running heads, may require data from several of these wrappers plus some generated text. Other formatting often requires that these elements be reordered.
If a RefDescriptor
is present, it should be used
for the short topic name. This name usually appears in the running
header along with the ManVolNum
in print media.
It may also appear in tables of contents and the index.
The InterfaceDefinition
element will be discarded in DocBook V4.0. It will no longer be available
in the content model of this element.
