Further glossary edits

Here are some possible Glossary edits:

>Transcript
>Transcripts are equivalent alternatives <#def-Equiv-Alternatives>
>for the sounds in an audio clip or an auditory track of a multimedia
>presentation. A "collated text transcript" for a video combines 
>(collates) caption text with text descriptions of video information
>(descriptions of the actions, body language, graphics, and scene
>changes of the visual track).

Possible Edit: Do we want to talk exclusively of equivalent 
alternatives for sounds. The second sentence also speaks of 
descriptions of video information. Should the first sentence also 
imply both?

>Transformation
>A transformation is a process that takes, as input, an object of Web 
>content <#def-Web-Content> in one format <#def-Format> and produces, 
>as output, a different object of Web content in the same format 
>(e.g., a function that transforms tables into lists).

Possible Edit: Do we want to include only transformations into the 
same format? Are all other transformations actually conversions?

>Typical Author
>     A person who possesses levels of authoring knowledge, authoring 
>tool proficiency, and experience with accessibility authoring 
>practices <#def-Acc-Auth-Practice> that are average as compared to 
>actual users of a particular authoring tool.

Possible Edit: I propose changing the last phrase to :
"that are average for users of a particular authoring tool."

We have no definition for:

>WCAG Techniques Documents
>     Web content (or just "content")
>Web Content
>     Web content (or just "content") ??? @@needs def@@

WCAG Techniques Documents can probably be removed or simply include a link.

How about a simple definition for Web Content:
Web Content:
Content published on the Web.
