Each time a link or button points to a document that can be downloaded, the following information must be included in the link text:
For example:
<a href="2011-annual-report.pdf">Download the 2011 annual report (PDF, 23 Mb)</a>
If symbols are used to visually indicate the format of documents that can be downloaded, make sure you include the image in the link text (hard-coded in the HTML code) and enter a value for the alternate text of the image.
For example:
<a href="2011-annual-report.pdf"> Download the 2011 annual report (23 Mb) <img src="images/pdf-symbol.png" alt="(PDF)" title="(PDF)" /> </a>
Sometimes, the text cannot be modified to include this information. In this case, and as a last resort, use the ''link'' or button title attribute to retrieve and complete the link or button text..
