Index entries to figures, tables, boxes

Index entries that are followed by an italic f, t, or b are index entries that refer to figures (f), tables (t), or boxes (b). Capture these as a cross reference to the milestone element representing the page containing the referenced figure, table, or box.

Capture the italic letters outside of the pageNum element, but within the xrefGrp that contains the pageNum and xref. Retain italics by capturing the letter in an i element.
