I have eight so far:

What I mean is that there are some tests that deal with where the file comes from and there are tests that deal with the file structure:

Where It Comes From:
	- http://dev.w3.org/webfonts/WOFF/spec/#conform-same-origin
	- http://dev.w3.org/webfonts/WOFF/spec/#conform-doc-origin
	- http://dev.w3.org/webfonts/WOFF/spec/#conform-css3font-available
	- http://dev.w3.org/webfonts/WOFF/spec/#conform-cors
Fire Structure:
	- http://dev.w3.org/webfonts/WOFF/spec/#conform-extraneous-reject
	- http://dev.w3.org/webfonts/WOFF/spec/#conform-overlap-reject
	- ...

I don't know the proper term for categorizing the same-orign, doc-orign, CSS3 and CORS tests. I hope this makes more sense.

Yes

Yes. This is what I was trying to get at last week on the call when I brought up the checksums. We have some testable assertions that are tagged with "file format" that could possibly be tagged with "user agent" as well. These are the ones that I have identified so far:

http://www.w3.org/Fonts/WG/wiki/TestPlan-UserAgent#Offset.2FLength_when_Metadata_and.2For_Private_Data_Not_Present
http://www.w3.org/Fonts/WG/wiki/TestPlan-UserAgent#Data_Block_Ordering
http://www.w3.org/Fonts/WG/wiki/TestPlan-UserAgent#Font_Table_Data_4-Byte_Boundary
http://www.w3.org/Fonts/WG/wiki/TestPlan-UserAgent#Table_Compressed_Length
http://www.w3.org/Fonts/WG/wiki/TestPlan-UserAgent#Table_Directory_Ascending_Order
http://www.w3.org/Fonts/WG/wiki/TestPlan-UserAgent#Table_Data_Compression_Format

I'm still trying to figure this out. Maybe I'll move them into appropriate sections and mark them as not being derived from testable assertions.

Probably. I'll add notes about this to the page.
