The <Substitute> element specifies a different font for producing the PDF file than was used in the original document. The replacement font must have the same font metrics as the original font. The original font name should be followed by the name of one or more real font names. The first matching replacement font found will be used. Arbortext Editor and Arbortext Publishing Engine use the first replacement font that matches the selection criteria. It’s optional and repeatable.

The <Substitute> element has one child element, <FontName>, which specifies the source and target font mapping. The target <FontName> is required and repeatable.

The <Substitute> element has no attributes.
