ref-type Type of Cross-Reference
Type of element that is the target of the cross-reference (for example, a figure (“fig”), a
table (“table”), or a footnote (“fn”). The
values may be used for type-specific processing or validation.
Usage/Remarks
The <xref> element may be used to reference anything that has an @id attribute. 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 tag sets. This attribute preserves the information from such tag sets concerning
the type of element to which the cross-reference is pointing.
