DITA addressing
DITA provides a number of facilities for establishing relationships
among DITA elements and between DITA elements and non-DITA resources. All DITA relationships
use
the same addressing facilities irrespective of the semantics of the relationship established.
DITA addresses are either direct, URI-based addresses, or indirect key-based addresses.
Within
DITA documents, individual elements are addressed by unique IDs specified on the common
@id
attribute. DITA defines two fragment identifier syntaxes for addressing DITA elements,
one for
topics and elements within maps and one for non-topic elements within topics.
