To map format names to DocBook elements of the same name, where possible:
[DocBookOptions]
; UseFormatAsTag = No (default, if tag unmapped use default elem),
; or Yes (if unmapped, use format name if valid in content
; model).
UseFormatAsTag = Yes
When UseFormatAsTag=Yes, any format with a name that is the same as a DocBook element name in the current content model is mapped to that element.
Unmapped format names that do not correspond to such element names are mapped to the default element; see:
§26.4.2.2 Specifying a default element for unmapped paragraph formats
§26.4.3.2 Specifying a default element for unmapped character formats.
