Accessibility Styles

Accessibility styles are used to ensure publications can be read by individuals with disabilities that impair access to the content of unstyled documents. ScML and the WFDW can build content (including ePub3, NIMAS, HTML, and proprietary formats) that meets current accessibility standards and works with assistive technologies, incorporating the augmentative information needed to achieve equality in content access.

Accessibility Styles

The following styles exist in Scribe Markup Language (ScML) to meet accessibility standards and apply to text that may render as italic and bold but convey specific meanings.

em emphasis
tnw title, name, or work
i change of voice
strong imperative statements
fterm foreign or technical terms
cite citations
taxspecies    species names

Note: Additional styles in ScML may render as italic, bold, small-caps, underline, or other text treatments. Examples include dispk for dialogue speaker, gt for glossary term, lang for foreign languages, and hemb for embedded heads. The complete list of ScML styles is found here.

Use the (i) style to indicate a change in voice, such as a thought or dream sequence.
