Ordered lists

Ordered List with nested ordered lists having an automatic (sitewide) list style that changes to lower alpha and lower roman because we set the style rules in MediaWiki:Common.css with

.mw-body ol {
 list-style-type:decimal
}
.mw-body ol li > ol {
 list-style-type:lower-alpha
}
.mw-body ol li > ol li > ol {
 list-style-type:lower-roman 
}
