Cross-reference (xref)

Also known as an xref. 

These are a fundamental components of the PageSeeder architecture and can be used in multiple ways, including the following:

• Assembling components (documents or  fragments) into a publication.
• Creating associations between document content.

Unlike links in conventional publishing applications or HTML, PageSeeder cross-references are rich structures that developers can customize or override. In PSML, cross-references are represented by the following elements:

• <xref>
• <blockxref>

Using labels or the xref config allows semantics to be attached to xrefs. This makes it possible to represent objects such as footnotes, end notes, citations and many other structures.
