Web Standard WCAG 2 3.1.1
Bad value for attribute
A BCP 47
lang attribute consists of hyphen-separated subtags. The first subtag identifies a natural language by its ISO 639 language code (e.g.
en for English) and may be followed by additional subtags. The most common additional subtag is a two-letter ISO 3166 country code (e.g.
GB for the United Kingdom to form
en-GB). IANA maintains a registry of allowed subtags. A empty
lang attribute is allowed (and means unknown language) but a
lang containing only spaces is not allowed and causes a random language to be selected in a screen reader.
Note: Section 508 Refresh (2017) checkpoints are equivalent to WCAG 2.0 level AA checkpoints.
