Location: Defines an ID as referring to the location of the <location> element. The <location> element enables a portion of a topic to serve as a destination for a hyperlink using the <link> or <xref> element.
The identifier for the current location, which can be used as a destination for hyperlinks.
The block of text where you want to assign the ID.
The <location> element is not needed at locations where there is already an element (such as <hometopic> or <figure>) that has a built-in ID or accommodates an author-defined id parameter.
Cross-references created with the <xref> element substitute the text between the <location> start and end tag for the <xref> element.
The following markup names a location and elsewhere creates a hyperlink to the location.
<s1 id=ConfigTopic> Configuration ... <location id=ConfigTopicBody>some text<\location> ... <s1 id=UseTopic> Usage ... See <link ConfigTopicBody>Configuration<\link> for additional information.
The advantage of linking to the ID in the <location> element is that the help window automatically scrolls to the point where the <location> tag is entered. In contrast, a link to the topic's ID ("ConfigTopic" in this case), always goes to the top of the topic.
The <location> element can also reference a position in your file using the predefined entity, (∅), as a placeholder.
Adding this markup at a key position in your file, allows you to create a link to that specific location:
paragraph text . . . <location id=pointA>∅<\location> . . .
