aria-valuemax
Defines the maximum allowed value for a range widget.
Widget attributes are specific to common user interface elements found on GUI systems or in rich internet applications which receive user input and process user actions. These attributes are used to support the widget roles.
Widget attributes might be mapped by a user agent to platform accessibility API state, for access by assistive technologies, or they might be accessed directly from the DOM. User agents MUST provide a way for assistive technologies to be notified when states change, either through DOM attribute change events or platform accessibility API events.

Description
Defines the maximum allowed value for a range widget.
Authors MUST ensure the value of aria-valuemax is greater than or equal to the value of aria-valuemin. If the aria-valuenow has a known maximum and minimum, the author SHOULD provide properties for aria-valuemax and aria-valuemin.
Note: A range widget starts with a given value, which can be increased until reaching the maximum value, defined by this property. Declaring the minimum and maximum values allows assistive technology to convey the size of the range to users.
