AH Formatter

In some cases, AH Formatter will map a general-purpose FO to the specialized Structure Element based on the context: for example, fo:inline ordinarily maps to ‘Span’, but the fo:inline child of fo:footnote maps to ‘Reference’ since the fo:inline is formatted to produce the footnote citation. Otherwise, to override the default mapping, specify the Structure Element name in the axf:pdftag property in XSL-FO or the -ah-pdftag property in CSS.
