An example would be page numbers, line numbers, etc. Using general-indirect-sosofo, you can apply arbitrary EL procedures to them. Typical example: formatting of page number references in an index according to the kind of reference (eg bold numbers for reference to a definition, italics otherwise...) I have once implemented that for the TeX backend using a two-pass approach: The TeX backend (or more accurately, jadetex) produces an auxiliary SGML file containing the needed page-numbers which are then made available in a second jade run via sgml-parse.
