Thanks for the email, Dmitri. The SVG WG had earlier extended an invitation to the OMA to work withthe SVG WG on the 1.2T test suite, but we did not get a response and I suspect the communication did not reach the right people - so, good to talk to you now.

Your requirements document has been received, and is on the agenda for the next face to face meeting, which happens next week in fact, in Cambridge MA.

We have some multi-feature test cases, although mostly we try to produce unit tests. We are certainly happy to add more.

As we become aware of untested features we add tests to cover them. We will be reviewing test coverage also at the f2f. If you have already started on a coverage analysis, we would be happy to see what you have so far and to work with you on combining with our work which is at

We would also be happy to work together to improve test coverage, and can supply you with documentation on how our tests are constructed.

Would OMA use cases be described in the "SVG in the Mobile Domain Requirements Document" document referenced from your communication? If so, do you have a direct link to it (rather than a link to the OMA home page).

We agree that the SMIL timing features can be tricky and require careful analysis. We have benefited in this area (and others) from advice from Dr Olaf Hofmann, and invited exert to the SVG WG.

In terms of features new to SVG Tiny 1.2, looking at the ones you mention, some are new to Tiny 1.2 9ie were not in Tiny 1.1) but have a long history in SVG (being ion SVG Basic 1.1 and SVG Full 1.1) so are well tested, since appropriate tests from the 1.1 Full test suite were converted to Tiny 1.2 tests:

?	Support for opacity, gradient
?	External element referencing

Others are indeed new in 1.2 and seeing their first use in Tiny 1.2:

?	Support for Multi line text and editable text
?	Support for multi media elements and their synchronization
?	Support for managing by discard and prefetch elements
?	Support for script execution and uDOM binding to the SVG DOM.
?	Introducing new concepts for event handling via listner and handlers 

Have you see the beta 1.2 test suite 9and associated implementation report) at

As a Sun employee you have W3C Member access so also please see our staging area for the test suite:
and the wiki page for test issues
and the test suite instructions

Please see the coverage page at
for our work towards that report.

DS> http://www.w3.org/QA/WG/2005/01/test-faq#enough

Yes, we are aware of that requirement. Lofton Henderson, chair of the QA WG, was previously involved in the SVG 1.1 test suite work.

DS> Development FAQ" (see link above).

DS> Is there any coverage report for SVG Tiny 1.2 Specification provided by
DS> SVG Tiny 1.2 test suite beta?
(see above)

DS> If no, is there a plan and preliminary date to create such report?

DS> Coverage measurement involves partitioning the specification. What is 
DS> the way for this partitioning your group choose? Feature, language

Logical sections (chapters and sections) and then testable assertions withing each. The convention for names of tests shows the chapter and section, see 

DS> What is the coverage goal for SVG Tiny 1.2 test suite.

We intend to cover each feature in the specification with at least a unit test. We aim to identify all testable assertions.

We do not aim at exhaustive combinatorial test (ie each value of each attribute in combination with each value of each other attribute).

DS> What the format of the coverage report you going to produce: mapping of
DS> tests to areas of the specification, more detailed report with binding
DS> of specification to tests and coverage numbers, etc?

Currently the links are from the test suite to the area of the specification that is primarily being tested. (Other areas are often tested too, for example all tests contain some text and most contain either paths, basic shapes or both with solid color fill. ).
