<topicref> elements are used to define keys, they also
can reference keys that are defined elsewhere. This topic explains how to evaluate key
<topicref> elements and its
For topic references that use the
@keyref attribute, the effective value
<topicref> element is determined in the following way:
<topicref>element is determined by resolving all intermediate key references. Each key reference is resolved either to a resource addressed directly by URI reference in an
@hrefattribute, or to no resource. Processors MAY impose reasonable limits on the number of intermediate key references that they will resolve. Processors SHOULD support at least three levels of key references.
@keyrefattribute cannot be determined until the key space has been constructed.
@lockmetaattribute is honored when metadata content is combined.
The combined attributes and content cascade from one map to another or from a map to a topic, but this is controlled by existing rules for cascading, which are not affected by the use of key references.
If, in addition to the
@keys attribute, a key definition specifies a
@keyref attribute that can be resolved after the key resolution
context for the key definition has been determined, the resources bound to the
referenced key definition take precedence.
