Cross referencing

The TopLeaf cross reference (Xref) facility is similar to index generation. The main difference is that Xref entries are independent rather than existing in a hierarchy.

Each Xref also contains information about how it was created, so different types of data can be easily extracted from the same file.

The Xref information can be used for a number of purposes, for example:

  • adding the page number of the target to the text of a link, or

  • creating a list of figures in the publication.
