Validating textbox using javascript

An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) must disclose the information in accordance with section 6 of the is a technical specification that provides a framework to improve the accessibility and interoperability of web content and applications.

Semantics is the science of meaning; in this case, used to assign roles, states, and properties that apply to user interface and content elements as a human would understand.

For instance, if a paragraph is semantically identified as such, assistive technologies can interact with it as a unit separable from the rest of the content, knowing the exact boundaries of that paragraph.

The schema to support this standard has been designed to be extensible so that custom roles can be created by extending base roles.

This allows user agents to support at least the base role, and user agents that support the custom role can provide enhanced access.

For example, web application developers create collapsible tree widgets in element.

To a non-disabled user, it may look and act like a collapsible tree widget, but without appropriate semantics, the tree widget may not be perceivable to, or operable by, a person with a disability because assistive technologies may not recognize the role.

Note that substantive technical comments were expected during the Candidate Recommendation review period that ended 13 January 2017.

Please see the Working Group's implementation report.

This role taxonomy includes interaction widgets and elements denoting document structure.

The role taxonomy describes inheritance and details the attributes each role supports.

Accessibility of web content requires semantic information about widgets, structures, and behaviors, in order to allow assistive technologies to convey appropriate information to persons with disabilities.
