A human-readable summary of specific accessibility features or deficiencies, consistent with the other accessibility metadata but expressing subtleties such as "short descriptions are present but long descriptions will be needed for non-visual users" or "short descriptions are present and no long descriptions are needed."
The summary is a brief, human-readable summary of features and/or deficiencies. It is used to indicate conformance to an accessibility standard or point out shortcomings to the standard.
The summary should not be a simple repetition of all the accessibility features and hazards.
Do not repeat this property unless it contains the summary in another language. In the case of
multiple summaries, use the
lang attributes to
differentiate the language.
