Recently discovered issue with WCAG2ICT definition of "document" - suggesting a new note to clarify

Hi gang,

As part of a wider review of WCAG2ICT (asking colleagues who aren't on 
the Task Force to look at it), I just discovered an issue with the 
definition of "document 
<http://www.w3.org/WAI/GL/wcag2ict/#keyterms_document>". The issue is 
that readers will see the term "document" and think "file", and 
therefore try to apply WCAG requirements to all manner of files (virus 
definition files and programming files were two specific concerns that 
came up from colleagues).

While our definition of "document" is based on the term "content 
<http://www.w3.org/WAI/GL/wcag2ict/#keyterms_content>" (which is scoped 
to "information and sensory experience to be communicated to the user"), 
I fear this fact is too easily missed.  Therefore, I propose that we add 
an additional Note to clarify this:

    Note: Software configuration and storage files such as databases and
    virus definitions, as well as computer instruction files such as
    source code, batch/script files, and firmware, are not examples of
    documents.  Such files are not "information and sensory experience
    to be communicated to the user" and therefore are not considered
    content.

I have added that note in context, as proposed "(New) Note 3" in red 
text as part of the full definition of document, below:

        *document (as used in WCAG2ICT)*

        assembly of content
        <http://www.w3.org/WAI/GL/wcag2ict/#keyterms_content>, such as a
        file, set of files, or streamed media that is not part of
        software and that does not include its own user agent

        *Note 1:***A documents always requires a user agent to present
        its content to the user.

        *Note 2:***Letters, spreadsheets, emails, books, pictures,
        presentations, and movies are examples of documents.

        *(New) Note 3: Software configuration and storage files such as
        databases and virus definitions, as well as computer instruction
        files such as source code, batch/script files, and firmware, are
        not examples of documents. Such files are not "information and
        sensory experience to be communicated to the user**"**and
        therefore are not considered content**.***

        *Note 3**4**:***Anything that can present its own content
        without involving a user agent, such as a self playing book, is
        not a document but is software.

        *Note 4**5**:***A single document may be composed of multiple
        files such as the video content, closed caption text, etc. This
        fact is not usually apparent to the end-user consuming the
        document / content. This is similar to how a single web page can
        be composed of content from multiple URIs (e.g. the page text,
        images, the JavaScript, a CSS file etc.).



I would like to propose this edit as part of the WCAG WG review next 
Tuesday July 9th, so it can get into the 3rd/final public draft that we 
publish later in July.

Any thoughts/edits before I do this as part of my WCAG WG "Ultimate? 
Survey" <https://www.w3.org/2002/09/wbs/35422/Ultimate/> response?
