Hyperlink templates
Hyperlink templates are sections in TemplateSpecification.xml that affect the behavior of Authoring Bridge.
When a user inserts an element with a name that matches the name attribute of one of the following templates, the Insert hyperlink browse dialog will be shown. When a user selects an object in this dialog, the content of the document fragment will be inserted in the target document in which selecteditem:href will be replaced by the logical ID of the selected object and selecteditem:text will be replaced by the text entered by the user on the dialog (navigation text for example).
For Example:
<template id="Dita.XRef.Template" name="xref">
<documentFragment>
<xref href="selecteditem:href">selecteditem:text</xref>
</documentFragment>
</template>
