(2) PLAIN LANGUAGE.—In this subsection, the term ‘‘plain language’’ means language that the intended audience, including individuals with limited English proficiency, can readily understand and use because that language is clean, concise, well-organized, and follows other best practices of plain language writing.
As if that wasn't bad enough, the government commissioner in charge of overseeing the regulations has this requirement:
"(3) GUIDANCE.—The Commissioner shall develop and issue guidance on best practices of plain language writing."
I guess that if the government doesn't tell us what 'plain language' is, we just don't know.
Now if only they'd only followed their own requirement in writing the bill in the first place.....
