Yes, that would be a better way of putting it. I don't want to bother people with the "geeky" side of design, but to highlight the additional features that can be incorporated into a Web site because standards are used properly.
I like to breeze over the main points, like keeping text sizes resizable in IE (lousy IE :mad: ) and automatically formatting pages for printing. I also say that they are easier to read for screen readers and style sheets can automatically format the pages for handheld devices.
I tell them it's like getting three Web sites for the price of one: A printable version, an on-screen version, and a handheld version (though I don't know of any complying devices yet). Each is more accessible to those with disabilities, which is good PR for your company and maybe even an untapped market.
People with moderate to severe vision problems have lower rates of Web usage, not because they don't want to, but because much of the Web is inaccessible or too hard for them to read.
And companies like untapped markets 
If people have questions about how this is done, then I'll get into the more geeky stuff, like source-ordered columns, title attributes in form input elements to aid screen readers, etc. I will then explain that CSS layouts separate the design from the content. If the company changes images, only a handfull of style sheets must be edited, not dozens (if not hundreds) of Web documents.
