(d'un certain texte de référence facile à trouver)
While alternate text may be very helpful, it must be handled with care. Authors should observe the following guidelines:
* Do not specify irrelevant alternate text when including images intended to format a page, for instance, alt="red ball" would be inappropriate for an image that adds a red ball for decorating a heading or paragraph. In such cases, the alternate text should be the empty string (""). (...)
* Do not specify meaningless alternate text (e.g., "dummy text"). Not only will this frustrate users, it will slow down user agents that must convert text to speech or braille output.
la norme c'est donc de se trimballer un attribut des fois (ou même souvent) sémantiquement inutile. bloat.
