Re: Complex tables: Scope AND id and header attributes

Thanks for your responses. My question stemmed from being required to use
both scope AND id and header attributes/arrays in complex tables on a PDF
file. The PDF files have tables that have headers two-levels of headers,
one of which spans multiple columns. The resource used was from the VA (
http://www.section508.va.gov/support/tutorials/pdf/Creating_Accessible_PDF_Tutorials_with_Acrobat_XI.pdf)
(page 47 - 51).

I'm going to follow the directions they gave and not argue, but I wanted
the opinion of the group and wanted to make sure that when I DON'T use both
I am still doing it correctly.

Thanks again!

Dona
