conformance, included/excluded technologies

As an action item, I was going to revise the section in conformance on included/excluded technologies.

Below is my revision. I have inserted comments in the text also (within square brackets, beginning the words: "E Hansen comment").

7. Web content technologies rendered. Identify each web content technology rendered by the user agent (for example, rendered as visual text, images, animation/video, audio [speech and/or non-speech], braille) [E Hansen comment: Can more specific examples be provided? What about MathML?] and categorize each such technology into one of the following lists.

a. Technologies relied upon. List the web content technologies that are relied upon to meet the claimed conformance level. By including a web content technology in this list, the claimant is asserting that the user agent meets the requirements of UAAG 2.0 at the claimed level when using that web content technology. This list must always contain at least one web content technology.

b. Technologies not relied upon. List the rendered web content technologies that are not relied upon (i.e., are not on the technology relied-upon list above). By including a web content technology in this technologies-not-relied-upon list, the claimant is not asserting that the user agent meets the requirements of UAAG 2.0 at the claimed level when using that that web content technology.

Note: A web content technology may be a combination of more than one other web content technology. For example, an image technology (e.g. PNG) might be listed together with a markup technology (e.g. HTML) since web content in the markup technology is used make web content in the image technology.[E Hansen comment: I find this confusing. I understand that PNG is a web content technology. But what is it that makes HTML a web content technology? Is it because HTML can be used to render visual text to a display? If that is not why, then why is HTML listed? Also, why is it necessary to HTML and PNG as a combination? Also, if they are a coherent pair, then does not that pair deserve its own special name? This example does not provide a name.]
