user-agent-supported [Priority AA]
implemented by user agents <del>and assistive technologies</del>[Are not ATs also user agents? See previous glossary entry]
Note: One of the factors that should be considered before adding a technology to a baseline is the availability of affordable user agents<del>and assistive technologies</del> which support the technology.
We removed the term "user-agent-supported" from the definition of programmatically determined, so it no longer occurs in the glossary.
The definition of "programmatically determined" now reads "determined by software from author-supplied data provided in a way that different user agents, including assistive technologies, can extract and present this information to users in different modalities".
