Response from the Working Group
================================
Conformance Requirement 1 requires that either all of the items for a
given conformance level are met *or* a conforming alternate version is
provided. Therefore, providing the conforming alternate version only
would meet the letter of the requirement. However, in the scenario you
describe, we suggest also using technique H53 to provide a short text
alternative for the Flash content and a link to the conforming
alternate version.
