I don't think yours is any broader.    Web content is defined as content fetched by a URL.    

RE excel sheets--    they can be referenced by a URL.   If the user agents will display them - then they are Web content.  If not -- then they wouldnít meet you definition of web content either I wouldnít think.  RIght?

The PDF financial tables and accompanying text were created from Ventura, which imported them using a process that converts spreadsheets into text for publication of hard copy. The ďspeadsheetsĒ as a result, after being imported are no longer tabular but rather text, comma delimited... no way to turn them into tables in the PDF tag tree, and not screen reader accessible. So they violate 1.3.1, and an incredible burden of over 5 years to migrate.
