I have added results for the TTV, TTX, and TTXV tools from the Timed Text
Toolkit (TTT) [1] to the IMSC1 Implementation Report (IR) [2]. At this
time, all tests are error free and produce no warnings.

The following description applies to these tools:

   - TTV - Timed Text Verifier - verifies syntactic and semantic
   constraints as defined by IMSC1 specification - effectively an IMSC
   Transformation Processor which output is one bit indicating verification
   results (GOOD, NO GOOD)
   - TTX - Timed Text Transformer - effectively an IMSC1 Transformation
   Processor which output is a sequence of ISD document instances
   - TTXV - Timed Text Transforming Verifier - effectively an IMSC1
   Transformation Processor which output is one bit indicating verification
   results (GOOD, NO GOOD)

As a note, the following content processing pipeline applies to the above:

   - TTV => TTX => TTXV

The distinction between TTV and TTXV is that the latter performs additional
semantic tests that can only be performed on post transformation ISD
instances.

At this time, all of the current W3C IMSC1 test files have been directly
incorporated into the TTXV test set [3], which ensures that all of the
IMSC1 test suite is valid and regularly tested.

An additional set of 76 IMSC1 test files [4][5], not included in the W3C
tests, are also utilized, which test the behavior related to semantic
proscriptions or recommended usage.

We anticipate further updates to the IR in early March in order to add
another column for the TTPE (Timed Text Presentation Engine) tool contained
in TTT.

Glenn
