Comments on WCAG 2.0 Conformance section, Editor's Draft

hello all,
Here are some comments to the WCAG 2.0 Conformance section, Editor's Draft at:
http://www.w3.org/WAI/GL/WCAG20/#conformance

1. The priority levels and how to conform to each level is clear for me now. 

2. In the explanation of each priority level I don't understand the following:
"In general, Level 1 success criteria achieve accessibility by supporting assistive technology while putting the fewest possible limits on presentation."
3. I also don't understand the following: 
"The success criteria in Level 2 provide additional support for assistive technology. At the same time, they also support direct access to content by the
many people who use conventional user agents without assistive technology."
What is meant with "direct access to content"  and what is meant with "additional support for assistive technology". 
4. Like Alan, I believe wrote, I also don't understand the following:
"For each success criterion, there is a list of techniques deemed by the Working Group to be sufficient to meet the requirement. For each sufficient technique,
there is a test to determine whether the technique has been successfully implemented. If the test(s) for a "sufficient" technique (or combination of techniques)
are passed, then that success criterion has been met. Passing all tests for all techniques is not necessary. It is also not necessary to meet a success
criterion using one of the sufficient techniques. There may be other techniques which are not documented by the working group that would also meet the
success criterion. When using such externally-provided techniques to meet WCAG 2.0 requirements, it is important that they be created by individuals or
organizations who are knowledgeable about the requirements of WCAG 2.0 and the needs of people with disabilities."
