Three attributes apply to list wrappers (ol, ul) and list items (li): type, start, and value; the first two apply only to list wrappers:
Before CSS, this was how you controlled lists.
By default, DITA2Go omits the type attribute from list wrappers ol and ul. To add the type attribute to list wrappers:
[CSS]
; NoAttribLists = Yes (default, omit type attribute from list tags),
; or No (include type, start, and value attributes in list tags)
NoAttribLists = No
; UseListTypeAttribute = Yes (default for JavaHelp, to fix CSS bug)
; or No (default for other formats, go by NoAttribLists value)
UseListTypeAttribute = Yes
Note: If you use both Mif2Go and DITA2Go, be aware that the default for NoAttribLists is No for Mif2Go.
When NoAttribLists=No, all three attributes are allowed on list tags.
When NoAttribLists=Yes, the value and start attributes are allowed, and use of the type attribute is left up to the value of UseListTypeAttribute, which defaults to No (meaning leave it up to NoAttribLists) except for JavaHelp and Oracle help, both of which need the type attribute.
