Reading over B.1.2, I note that we always say "transformations and 
conversions". This is wordy and since the requirement apply to both, I 
think we could define a common term.

Looking around I found the concept of "Web content transformations" here 
http://www.w3.org/TR/ct-guidelines/#sec-types-of-transformation

We might then say...

DEFN:
Web Content Transformation:
A process that takes as input, content in one web content technology or 
non-web content technology (e.g., a word processing format) and produces 
as output, Web content that has been restructured (linearizing tables, 
splitting a document into pages), re-coded (e.g., HTML to XHTML, a word 
processing format to HTML) or optimized (e.g., removing whitespace, 
re-compressing images).


B.1.2.1 End Product Preserves Accessibility Information: Any 
*accessibility information (WCAG 2.0 Level A)* recognized in the input 
to any web content transformation is preserved in the output in a way 
that is available to end users, if allowed by the web content technology 
of the output. (Level A)

B.1.2.2 End Product Cannot Preserve Accessibility Information: If the 
web content technology of the output of a web content transformation 
cannot preserve recognized *accessibility information (WCAG 2.0 Level 
A)*, then at least one of the following are true: (Level A)
(a) Option to Save: the authoring tool provides the author(s) with the 
option to save the accessibility information in another way (e.g., as a 
"comment", as a backup copy of the input); or
(b) Warning: the authoring tool notifies the author(s) that this will 
result in web content accessibility problems in the output.

B.1.2.3 Accessibility Information Preservation (Enhanced): Any 
accessibility information (up to WCAG 2.0 Level AAA) recognized in the 
input to any web content transformation is preserved in the output in a 
way that is available to end users. (Level AA)
