The Timed Text Working Group invites implementation of the Candidate Recommendation of TTML Text and Image Profiles for Internet Media Subtitles and Captions 1.0.
This document specifies two profiles of TTML1: a text-only profile and
an image-only profile. These profiles are intended to be used across
subtitle and caption delivery applications worldwide, thereby
simplifying interoperability, consistent rendering and conversion to
other subtitling and captioning formats. The text profile is a superset
of TTML Simple Delivery Profile for Closed Captions (US). Learn more
about the Video in the Web Activity.

Last Call: Canonical EXI
The Efficient XML Interchange Working Group has published a Last Call Working Draft of Canonical EXI.
Any EXI document is part of a set of EXI documents that are logically
equivalent within an application context, but which vary in physical
representation based on differences permitted by the Efficient XML
Interchange (EXI) Format 1.0 (Second Edition). This specification
describes a relatively simple method for generating a physical
representation, the canonical form, of an EXI document that accounts for
the permissible changes. An example of the applications targeted by
this specification is one that needs to guarantee non-repudiation using
XML Signature yet allows certain flexibility for intermediaries to
reconstitute the documents before they reach final destination without
breaking the signatures. Note that two documents may have differing
canonical forms yet still be equivalent in a given context based on more
elaborate application-specific equivalence rules which is out of scope
of this specification. Comments are welcome through 16 July. Learn more about the Extensible Markup Language (XML) Activity.
