Description James Craig 2013-10-02 01:20:10 PDT 
WebSpeech: SpeechSynthesisUtterance does not strip XML from SSML text; speaks literal markup.

From https://dvcs.w3.org/hg/speech-api/raw-file/9a0075d25326/speechapi.html#utterance-attributes
"[the text] may be either plain text or a complete, well-formed SSML document. [SSML] For speech synthesis engines that do not support SSML, or only support certain tags, the user agent or speech engine must strip away the tags they do not support and speak the text."


XML markup examples in the SSML spec:
