Pull content into topics (topicpull)
topicpull step pulls content into
<link> elements. This step is implemented in XSLT.
<xref> element does not contain link text, the target is examined and the link text is
pulled. For example, a reference to a topic pulls the title of the topic; a reference to a list item pulls the
number of the item. If the
<xref> element references a topic that has a short
description, and the
<xref> element does not already contain a child
<desc> element, a
<desc> element is created that contains the
text from the topic short description.
The process is similar for
<link> elements. If the
<link> element does
not have a child
<linktext> element, one is created with the appropriate link text.
Similarly, if the
<link> element does not have a child
element, and the short description of the target can be determined, a
<desc> element is
created that contains the text from the topic short description.
