<!--
Test cases for Touch Events v1 Recommendation
http://www.w3.org/TR/touch-events/
These tests are based on Mozilla-Nokia-Google's single-touch
tests and to some extent Olli Pettay's multi-touch tests.
The primary purpose of the tests in this document is checking that the
various interfaces of the Touch Events APIs are correctly implemented.
Other interactions are covered in other test files.
This document references Test Assertions (abbrev TA below) written by Cathy Chan
http://www.w3.org/2010/webevents/wiki/TestAssertions
