Italic/emphasized text can be achieved by using one of the following tags: "i", "em" or "emphasize". The optional "class" parameter allows the use of a desired CSS class. Usage:

<i [class=""] [custom_parameter="" [...] ]>Emphasized text.</i>

or

<em [class=""] [custom_parameter="" [...] ]>Emphasized text.</em>

or

<emphasize [class=""] [custom_parameter="" [...] ]>Emphasized text.</emphasize>

The custom parameters are optional. Their names must be specified using the "CustomAttributes[]" array in the [emphasize] block within an override for the "content.ini" configuration file. When used, a custom parameter will be available as a template variable with the same name as it was specified in the tag itself.
