14.2. Extending Tile Definitions
Problem
You want to create a new Tiles definition that reuses a similar one.
Solution
When you define a new definition in your Tiles definition file
(tiles-def.xml), you can specify a definition to
extend using the
extends="definitionName"
attribute. The new definition inherits attributes of the extended
definition and can override attribute values. (See Example 14-5.)
