Why are there now divergent requirements?
The HTML conformance requirement takes into account the accessibility and usability needs of users:
- They have a very slow connection and are browsing with images disabled.
- They have a vision impairment and use text to speech software.
- They have a cognitive impairment and use text to speech software.
- They are using a text-only browser.
- They are listening to the page being read out by a voice Web browser.
- They have images disabled to save on download costs.
- They have problems loading images or the source of an image is wrong.
