3.4.2.2 The keys attribute
A keys attribute consists of one or more space-separated
keys. Map authors define keys using a topicref or topicref specialization
that contains the “keys” attribute. Each key definition introduces
a global identifier for a resource referenced from a map. Keys resolve
to the resources given as the href value on the key definition topicref
element, to content contained within the key definition topicref element,
or both.
The @keys attribute uses
the following syntax:
- The value of the @keys attribute is one or more
space separated key names.
- Key names consist of characters that are legal
in a URI. The case of key names is significant.
- The following characters are prohibited in key names:
"{", "}", "[", "]", "/", "#", "?", and whitespace characters.
A key may not resolve to sub-topic elements, although
a keyref attribute may do so by combining a key with a sub-topic element
id.
