However, I think the example is appropriate to current practice-- there are many sites that provide separate links to high- and low-bandwidth versions of multimedia objects, and the link text often fails to identify the target clearly.

Table with 3 columns and 2 rows Graphic Quick Time Link graphic play low bandwidth version of this video Link graphic play high bandwidth version of this video Graphic Real Media Link graphic play low bandwidth version of this video Link graphic play high bandwidth version of this video Table end This is on the home page of a major University Web site, specifically intended to make University resources available to all citizens of the state of Texas.
