Just for those not familiar with these guidelines. 

ISO 16071 is now 9142-171 and is heading for Candidate Draft. 
It is originally based upon (and is harmonized with) HFES 200.3

Both are software accessibility guidelines. 

StickyKeys and functions like it are supposed to be done in OS and honored
by applications.  But if an operating environment overrides the OS then it
inherits the responsibility for providing the OS functions. 


PS  I have been helping to coordinate and harmonize between WCAG 2.0 and
both of these developing standards.

Java is an application enviroment, with its own rules (java, for default,
hereditate only Java configuration like font, etc. And cannot hereditate OS
Like in ex-ISO 16071 (formely ISO 9241-171), these requirements involve
software applications interfaces that can only be applied following OS
accessibility or ISO standards (W3C don't define accessibility for software
interfaces), like Section 508 paragraph that you cited.

    Oggetto: Missing criteria from WCAG 2.0?
    I am continuing to work on a mapping from 508 to WCAG 2.0.  It seems to
me the following items are referenced by 1194.21 but not by WCAG 2.0.  Are
these items applicable to Java apps?
    (b) Applications shall not disrupt or disable activated features of
other products that are identified as accessibility features, where those
features are developed and documented according to industry standards.
Applications also shall not disrupt or disable activated features of any
operating system that are identified as accessibility features where the
application programming interface for those accessibility features has been
documented by the manufacturer of the operating system and is available to
the product developer.
    (g) Applications shall not override user selected contrast and color
selections and other individual display attributes. 
    (j) When a product permits a user to adjust color and contrast settings,
a variety of color selections capable of producing a range of contrast
levels shall be provided.
    Thanks for your consideration.
