Here are comments in response to your request for review of the
"Speech Synthesis Markup Language Specification for the Speech Interface
Framework" Last Call Working Draft [1].

The title "Speech Synthesis Markup Language Specification for the
Speech Interface Framework" is quite long. How does "Speech
Synthesis Markup Language (SSML) Specification Version 1.0" sound?

The references need development and could work without hopping to
other specs. In 1., JSML can be a link [JSML] to your normative
references in section 7. In 1.3, 2.8, and 2.9 there can be a link
[CSS2]. In 2.2, I would use XML 1.0 section 2.12 as the authority
with a [XML] link to your normative references.

These documents could all be normative references rather than links
in the running text; I may have missed some:
Speech Synthesis Markup Requirements for Voice Markup Languages
Cascading Style Sheets, level 2
RFC 1766
Extensible Markup Language (XML) 1.0 (Second Edition)
Namespaces in XML
International Phonetic Alphabet
ASCII Phonetic Symbols for the World's Languages: Worldbet
Computer-coding the IPA: a proposed extension of SAMPA

A good model is HTML at http://www.w3.org/TR/html401/references.html.
(The definition terms like [CSS2] can be black.)

Just a comment that the introduction especially 1.2 is very helpful.

Below, a section number is followed by a quote and then a suggestion.
