By default, the content of most elements is included in all output media. Within maps and topics, elements can specify the delivery targets to which they apply.
Within maps, topic references can use the @deliveryTarget attribute to
indicate the delivery targets to which they apply. Within topics, most elements can use
the @deliveryTarget attribute to indicate the delivery targets.
If a referenced topic should be excluded from all output formats, set the
@processing-role attribute to resource-only instead of using the
@deliveryTarget attribute. Content within that topic can still be
referenced for display in other locations.
@deliveryTarget@print attribute.The @deliveryTarget
attribute is specialized from the @props attribute. It is defined
in the deliveryTargetAttDomain, which is integrated into all OASIS-provided
document-type shells. If this domain is not integrated into a given document-type
shell, the @deliveryTarget attribute will not be
available.
The @deliveryTarget attribute is processed the same way as any other
conditional processing attribute. For example, <topicref deliveryTarget="html5
epub" href="example.dita"/> uses two values for
@deliveryTarget. A conditional processing profile can then set rules
for @deliveryTarget that determine whether the topic is included or
excluded when the map is rendered as HTML5 or EPUB.
