The objective of this failure condition is to address situations where the non-text content is updated, but the text alternative is not updated at the same time. If the text in the text alternative can not still be used in place of the non-text content without losing information or function, then it fails because it is no longer a text alternative for the non-text content.
Failure Example 1: A Sales chart is updated to October results, but the text alternative still describes September results.
Failure Example 2: Pictures on a home page change daily, but text alternatives are not updated at the same time.
