The PDF export is now generating internal links as much as possible. By internal links we mean links that make the PDF viewer scroll the target content into view rather than opening it in a web browser. The following types of internal links are supported:

• links to a fragment from the same page that is included in the PDF export (e.g. #HDescription)
• links to a fragment from another page that is included in the PDF export (e.g. /xwiki/bin/view/Other/Page#HDescription)
• links to another page that is included in the PDF export (e.g. /xwiki/bin/view/Other/Page)

Internal links that use fragment identifiers are updated automatically, before printing the content to PDF, to target the corresponding global fragment identifier that is generated by the shared id generator used when rendering multiple pages for PDF export. In other words, having multiple sections with the same name in the PDF export shouldn't cause any problems because the links that target them are updated properly.
