Did we miss a substitution in the Note for 1.4.2?

Hi gang,

Looking at our latest working draft, at 
http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#visual-audio-contrast-dis-audio 
I noticed that we appear to have missed a few "web page" substitutions 
in the Note.

Here's our additional guidance for 1.4.2:

    This applies directly as written, and as described in INTENT from
    Understanding WCAG 2.0 (above) replacing "on a Web page" with "in a
    non-web document
    <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#documentdef> or
    software
    <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_softwaredef>
    " and "any content" with "any part of a non-web document
    <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_documentdef>
    or software
    <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_softwaredef>".


    With these substitutions, it would read:

        1.4.2 Audio Control: If any audio in a non-web document
        <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_documentdef>
        or software
        <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_softwaredef>
        plays automatically for more than 3 seconds, either a mechanism
        is available to pause or stop the audio, or a mechanism is
        available to control audio volume independently from the overall
        system volume level. (Level A)

        *Note: *Since any part of a non-web document
        <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_documentdef>
        or software
        <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_softwaredef>
        that does not meet this success criterion can interfere with a
        user's ability to use the whole page, all content on the Web
        page (whether or not it is used to meet other success criteria)
        must meet this success criterion. See Conformance Requirement 5:
        Non-Interference.


I noticed this while doing a compare with the 5Dec12 M376 EN, which 
states for 1.4.2 for software:

    *1.4.2 Audio Control:*If any audio in software plays automatically
    for more than 3 seconds, either a mechanism is available to pause or
    stop the audio, or a mechanism is available to control audio volume
    independently from the overall system volume level. (Level A)

    Since any content that does not meet this success criterion can
    interfere with a user's ability to use the software application, all
    content in the software (whether or not it is used to meet other
    success criteria) must meet this success criterion. See WCAG 2.0
    Conformance Requirement 5: Non-Interference.



I think we need to spell out further substitutions.  To wit:

    This applies directly as written, and as described in INTENT from
    Understanding WCAG 2.0 (above) replacing "on a Web page" with "in a
    non-web document
    <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#documentdef> or
    software
    <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_softwaredef>
    ", *"whole page" with "whole document or software"*, *"on the Web
    page" with "in the document or software"* and "any content" with
    "any part of a non-web document
    <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_documentdef>
    or software
    <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_softwaredef>".


    With these substitutions, it would read:

        1.4.2 Audio Control: If any audio in a non-web document
        <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_documentdef>
        or software
        <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_softwaredef>
        plays automatically for more than 3 seconds, either a mechanism
        is available to pause or stop the audio, or a mechanism is
        available to control audio volume independently from the overall
        system volume level. (Level A)

        *Note: *Since any part of a non-web document
        <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_documentdef>
        or software
        <http://www.w3.org/WAI/GL/2012/WD-wcag2ict-20121126/#wcag2ict_softwaredef>
        that does not meet this success criterion can interfere with a
        user's ability to use the *whole document or software*, all
        content *in the document or software* (whether or not it is used
        to meet other success criteria) must meet this success
        criterion. See Conformance Requirement 5: Non-Interference.


We could also go with the M376 language, and start our Note with "Since 
any content that does not meet..." as they do, but we'd have a more 
complex substitution to describe in prose that way.


Is this something we can address (and resolve) in e-mail NOW?  Or 
perhaps as part of the WCAG WG meeting on Thursday?

Sorry I didn't notice it earlier...
