The Working Group never formally addressed this comment (the responses
are not public) and the new draft states "SVG User Agents must implement
progressive rendering although there is no minimum rendering update
frequency required for conformance." It's not possible to tell the
difference between no support for progressive rendering and support for
it where the document is only updated once the document is fully loaded,
so this does not address my concern.

One way to address it would be to update the requirements document and
clearly point out there and the draft that SVG Tiny 1.2 does have
optional features. In this case the weird requirement cited above should
be rephrased accordingly.
