KERML11 — Suspicious use of the term 'front' instead of "font"

The following sentence looks suspicious with the use of the term 'front' instead of 'font' that is used associated with the 'code' font.

Similar stylistic conventions apply to text about KerML models, except that an "italic code" front is used.

It may be intentional to use the term "front", as it is a variation or a typeface of a specific font. But I doubt this is your intention because the term 'front' is not used in different dictionary or encyclopedic sources that I consulted. They are rather using italic or bold font, form or typeface.
