Example: Duplicate key definitions across multiple maps
In the following example, a root map contains a key definition for the key "toner-specs" and references to two submaps.
<map> <keydef keys="toner-specs" href="toner-type-a-specs.dita"/> <mapref href="submap-01.ditamap"/> <mapref href="submap-02.ditamap"/> </map>
The first submap, submap-01.ditamap
, contains definitions for the keys "toner-specs" and "toner-handling":
<map> <keydef keys="toner-specs" href="toner-type-b-specs.dita"/> <keydef keys="toner-handling" href="toner-type-b-handling.dita"/> </map>
The second submap, submap-02.ditamap
, contains definitions for the keys "toner-specs", "toner-handling", and "toner-disposal":
<map> <keydef keys="toner-specs" href="toner-type-c-specs.dita"/> <keydef keys="toner-handling" href="toner-type-c-handling.dita"/> <keydef keys="toner-disposal" href="toner-type-c-disposal.dita"/> </map>
For this example, the effective key definitions are listed in the following table.
Key | Bound resource |
---|---|
toner-specs | toner-type-a-specs.dita |
toner-handling | toner-type-b-handling.dita |
toner-disposal | toner-type-c-disposal.dita |
The key definition for "toner-specs" in the root map is effective, because it is the
first
encountered in a breadth-first traversal of the root map. The key definition for
"toner-handling" in submap-01.ditamap
is effective, because submap-01 is
included before submap-02 and so comes first in a breadth-first traversal of the submaps.
The
key definition for "toner-disposal" is effective because it is the only definition
of the
key.
