<xref>

X(cross) Reference

Used for any kind of internal article referencing

Remarks

This element may be used to reference anything that has an attribute of type @id. This single element takes the place of the many named types of references (such as figure references, table references, and footnote references) that are common in many journal Tag Sets.

The @ref-type attribute (of the <xref> element) can be used to preserve information concerning what type of element is being pointed to by the cross-reference.

Display/Formatting Note: The content of the reference (if present) will be displayed as the link.
