This is an early access version, made available for early testing and evaluation.
The Z39.86 SSML Integration Feature recasts a subset of the W3C Speech Synthesis Markup Language (SSML) Version 1.1 as a Feature for incorporation in Z39.86-2010 Profiles.
The Z39.86 SSML Integration Feature targets authoring contexts where speech output is targeted. The feature's content model definitions are designed so that a Processing Agent can safely ignore the SSML fragments when speech-related information is not relevant.
Each element of the feature fully inherits the corresponding semantics as defined by SSML 1.1.
This feature is maintained by the ANSI/NISO Z39.86 advisory committee under the auspices of NISO.
In speech-output processing contexts, Processing Agents should process each encountered element or attribute in the SSML namespace as dictated by the SSML 1.1 specification.
Upon encountering the ph and associated alphabet attributes on a non-SSML namespace element,
a Processing Agent should process the element equally to the SSML phoneme element.
Processing Agents should consider the Z39.86 w element as equal to the SSML token element.
Processing Agents that fail to meet the above behavioral expectations should issue a warning.
In non-speech-output processing contexts, a Processing Agent must ignore any encountered XML element in the SSML namespace, and continue processing its children. Attributes in the SSML namespace occuring on non-SSML namespace elements must also be ignored.
