.LP
It is also possible to load a keyboard geometry by name. The X server maintains
a database
of keyboard components (see below).
.I XkbGetNamedGeometry
can return BadName if the name cannot be found.
The X server maintains a database of keyboard components, identified by
component type.
The database contains all the information necessary to build a complete keyboard
description for a particular device, as well as to assemble partial
descriptions. Table 1 identifies the component types and the type of information
they contain.

.TE
While a keymap is a database entry for a complete keyboard description, and
therefore
logically different from the individual component database entries, the rules
for
processing keymap entries are identical to those for the individual components.
In the
discussion that follows, the term component is used to refer to either
individual
components or a keymap.
There may be multiple entries for each of the component types. An entry may be
either
.I complete
or
.I partial.
Partial entries describe only a piece of the corresponding keyboard component
and are
designed to be combined with other entries of the same type to form a complete
entry.
For example, a partial symbols map might describe the differences between a
common ASCII
keyboard and some national layout. Such a partial map is not useful on its own
because it
does not include those symbols that are the same on both the ASCII and national
layouts
(such as function keys). On the other hand, this partial map can be used to
configure
.I any
ASCII keyboard to use a national layout.
When a keyboard description is built, the components are processed in the order
in which
they appear in Table 1; later definitions override earlier ones.
