Inlined elements are called "Text Range Elements" in F+S. Probably "inline" is not the correct word to use. I am talking about elements that are used for special formatting inside a same paragraph (in typographical terms). E.g something like <body> This is <emph>super</emph> cool </body>
The important bit is to insert " TextRangeFormatting " in the beginning of a Context rule. You must realize that this rule is of a different sort, albeit still a Container. Look at the source of this document and the Stepbystep-edd.fm file if it's not clear. Basically you want to change a simple thing, like font family, angle or weight.
