Schema name: Simple Content Format

txt element

clr element

None.

While bold is recommended for emphasis, the manner of emphasis is up to individual Windows SideShow-compatible devices. If a device cannot emphasize text by using formatting, it may surround the text to be emphasized with other appropriate characters, such as quotes.

The EmphasisType complexType defines the type that allows for the em element to occur within the txt element, interspersed with both text and one or more instances of the clr element.

<txt>I <em>wish</em> I had a Windows SideShow-compatible device!</txt>
