If something a person does to a thing causes it to change then the change is reflected in the code<\/p>\n
a person can<\/h3>\n

- Press something – aria-pressed<\/a><\/li>\n
- Check something – aria-checked<\/a><\/li>\n
- Select something aria-selected<\/a><\/li>\n
- Expand or collapse something – aria-expanded<\/a><\/li>\n
- Change the value of a thing aria-valuenow<\/a>, aria-valuetext<\/a><\/li>\n
- Change the order of something aria-sort<\/a><\/li>\n
- Change the validity of something aria-invalid<\/a><\/li>\n<\/ul>\n

\n
- make something that is required, un-required – aria-required<\/a><\/li>\n
- make something controlled, uncontrolled – aria-controls<\/a><\/li>\n
- make some not flow to where it flows – aria-flowto<\/a><\/li>\n
- stop something being busy – aria-busy<\/a><\/li>\n
- disown something that is owned –\u00a0aria-owns<\/a><\/li>\n<\/ul>\n
not user modifiable<\/h3>\n
If the value of property cannot be set by the user it is not covered by 4.1.2 Name, Role, Value (Level A)<\/a>. So when a testing tool or some titular authority figure states that a lack of an
aria-controls<\/code> attribute, for example,\u00a0 is a failure of 4.1.2 it is wrong<\/strong><\/p>\nFurther listening
