Fixing Language Errors
After you convert documents to accessible PDF, there is a good chance you will run into a language error problem. You may see this error message after running the Accessibility Checker in Adobe Acrobat 5. You can easily fix this problem in Acrobat 5 by changing the language setting for the structure of the document. Here's how to do it:
Select Window, Tags. The Tags window displays the logical structure tree of the document.
Expand the list by clicking on the plus (+) sign next to the first root element in the list. The list expands to show nested elements.
Click one time on the highest element level in the list, under which all other elements fall (see Figure 4). Do not click on the first root element for this exercise.
Figure 4 Select the highest element in the list to make changes to all subelements in the structure.
In the Tags palette, select Tags, Element Properties. The Element Properties window is displayed.
In the Main Properties pane, click on the down arrow next to the Language field. The pull-down menu appears.
Select EN-US from the list for U.S. English. Click OK when you have finished. You are returned to the document window. If you run the Accessibility checker again, the language is no longer a problem.
