Jeanne has asked me to provide potential re-wordings to make the SCs identified in my message (http://lists.w3.org/Archives/Public/w3c-wai-au/2013AprJun/0047.html) more positively implementable:


REWORDED: A.3.2.1 Auto-Save (Minimum): The authoring tools does not include session time limits or the authoring tool can be set to automatically save web content edits made using the authoring tool before the session time limits are reached. (Level A)

ORIGINAL: A.3.2.1 Auto-Save (Minimum): If the authoring tool includes authoring session time limits, then the authoring tool can be set to automatically save web content edits made using the authoring tool before the session time limits are reached. (Level A)

---

REWORDED: A.3.2.2 Timing Adjustable: The authoring tool does not include time limits or at least one of the following is true: (Level A)
(a) Turn Off: Authors are allowed to turn off the time limit before encountering it; or
(b) Adjust: Authors are allowed to adjust the time limit before encountering it over a wide range that is at least ten times the length of the default setting; or
(c) Extend: Authors are warned before time expires and given at least 20 seconds to extend the time limit with a simple action (e.g., "press the space bar"), and authors are allowed to extend the time limit at least ten times; or
(d) Real-time Exception: The time limit is a required part of a real-time event (e.g., a collaborative authoring system), and no alternative to the time limit is possible; or
(e) Essential Exception: The time limit is essential and extending it would invalidate the activity; or
(f) 20 Hour Exception: The time limit is longer than 20 hours.

ORIGINAL: A.3.2.2 Timing Adjustable: If a time limit is set by the authoring tool, then at least one of the following is true: (Level A)
(a) Turn Off: Authors are allowed to turn off the time limit before encountering it; or
(b) Adjust: Authors are allowed to adjust the time limit before encountering it over a wide range that is at least ten times the length of the default setting; or
(c) Extend: Authors are warned before time expires and given at least 20 seconds to extend the time limit with a simple action (e.g., "press the space bar"), and authors are allowed to extend the time limit at least ten times; or
(d) Real-time Exception: The time limit is a required part of a real-time event (e.g., a collaborative authoring system), and no alternative to the time limit is possible; or
(e) Essential Exception: The time limit is essential and extending it would invalidate the activity; or
(f) 20 Hour Exception: The time limit is longer than 20 hours.

REWORDED: A.3.2.3 Static Input Components: The authoring tool does not include moving user interface components that accept input or authors can pause the movement. (Level A)

ORIGINAL: A.3.2.3 Static Input Components: If authoring tool user interface components accept input and move, then authors can pause the movement. (Level A)

---

NOTE: For A.3.3.1 I just simplified and removed "automatically" from the IF condition.:
REWORDED A.3.3.1 Static View Option: If an editing-view can render and play visual time-based content, then the playing can be paused and can be set to not play automatically. (Level A)

ORIGINAL: A.3.3.1 Static View Option: If the authoring tool contains editing-views that render and play visual time-based content automatically, then those editing-views can be paused and can be set to not play automatically. (Level A)

---

REWORDED: B.1.1.1 Content Auto-Generation After Authoring Sessions (WCAG): The authoring tool does not automatically generate web content after the end of an authoring session or authors can specify that the content be accessible web content (WCAG). (Level A to meet WCAG 2.0 Level A success criteria; Level AA to meet WCAG 2.0 Level A and AA success criteria; Level AAA to meet all WCAG 2.0 success criteria)
- Note: This success criterion applies only to automatic processes specified by the authoring tool developer. It does not apply when author actions prevent generation of accessible web content (WCAG).

ORIGINAL: B.1.1.1 Content Auto-Generation After Authoring Sessions (WCAG): If the authoring tool provides the functionality for automatically generating web content after the end of an authoring session, authors can specify that the content be accessible web content (WCAG). (Level A to meet WCAG 2.0 Level A success criteria; Level AA to meet WCAG 2.0 Level A and AA success criteria; Level AAA to meet all WCAG 2.0 success criteria)
- Note: This success criterion applies only to automatic processes specified by the authoring tool developer. It does not apply when author actions prevent generation of accessible web content (WCAG).

REWORDED: B.2.1.1 Accessible Content Possible (WCAG): The authoring tool does not place restrictions on the web content that authors can specify or those restrictions do not prevent WCAG 2.0 success criteria from being met. (Level A to meet WCAG 2.0 Level A success criteria; Level AA to meet WCAG 2.0 Level A and AA success criteria; Level AAA to meet all WCAG 2.0 success criteria)

ORIGINAL: B.2.1.1 Accessible Content Possible (WCAG): If the authoring tool places restrictions on the web content that authors can specify, then those restrictions do not prevent WCAG 2.0 success criteria from being met. (Level A to meet WCAG 2.0 Level A success criteria; Level AA to meet WCAG 2.0 Level A and AA success criteria; Level AAA to meet all WCAG 2.0 success criteria)

REWORDED: B.2.3.2 Repair of Text Alternatives During Authoring Sessions: The authoring tool does not attempt to automatically or semi-automatically repair text alternatives for non-text content ("repair strings") during an authoring session or the following are both true: (Level A)
    (a) No Generic or Irrelevant Strings: Generic strings (e.g. "image") and irrelevant strings (e.g., the file name, file format) are not offered as repair strings; and
    (b) Author Control: Authors have the opportunity to accept, modify, or reject the repair strings prior to insertion in the content.

ORIGINAL: B.2.3.2 Repair of Text Alternatives During Authoring Sessions: If the authoring tool attempts to automatically or semi-automatically repair text alternatives for non-text content ("repair strings") during an authoring session, then the following are both true: (Level A)
    (a) No Generic or Irrelevant Strings: Generic strings (e.g. "image") and irrelevant strings (e.g., the file name, file format) are not offered as repair strings; and
    (b) Author Control: Authors have the opportunity to accept, modify, or reject the repair strings prior to insertion in the content.

REWORDED: B.2.3.3 Repair of Text Alternatives After Authoring Sessions: The authoring tool does not attempt to automatically repair text alternatives for non-text content after an authoring session has ended or the following are both true: (Level A)
    (a) No Generic or Irrelevant Strings: Generic strings (e.g. "image") and irrelevant strings (e.g., the file name, file format) are not used as repair strings; and
    (b) Author Control: In the subsequent authoring session (if any), auto-generated text alternatives are indicated and authors have the opportunity to accept, modify, or reject the text alternatives.

ORIGINAL: B.2.3.3 Repair of Text Alternatives After Authoring Sessions: If the authoring tool attempts to automatically repair text alternatives for non-text content after an authoring session has ended, then the following are both true: (Level A)
    (a) No Generic or Irrelevant Strings: Generic strings (e.g. "image") and irrelevant strings (e.g., the file name, file format) are not used as repair strings; and

REWORDED: B.4.1.2 Option to Reactivate Features: The authoring tool does not include the option to turn off its accessible content support features or the features can be turned back on. (Level A)

ORIGINAL: B.4.1.2 Option to Reactivate Features: If authors can turn off an accessible content support feature, then they can turn the feature back on. (Level A)

---

REWORDED: B.4.1.3 Feature Deactivation Warning: The authoring tool does not include the option to turn off its accessible content support features or, when turning off these features, authors are informed that this may increase the risk of content accessibility problems (WCAG). (Level AA)

ORIGINAL: B.4.1.3 Feature Deactivation Warning: If authors turn off an accessible content support feature, then the authoring tool informs them that this may increase the risk of content accessibility problems (WCAG). (Level AA)
