My understanding is just the opposite: conformance is defined for 
documents, not just for serializations. For example, a document that 
inserts, with JavaScript, a title element inside a body element is just 
as nonconforming as one with the markup <body><title>foo</title></body>.

Regarding my example that assigns an onpaste event handler, the question 
really is whether it counts as an attribute. HTML5 terminology is 
somewhat confusing, but presumably "attribute" means both content 
attributes and IDL attributes in the requirement

"Authors must not use elements, attributes, or attribute values that are 
not permitted by this specification or other applicable specifications"

at 3.2.1 Semantics (http://www.w3.org/TR/html5/dom.html#semantics-0), a 
somewhat odd place for a requirement that is (mostly) syntactic.

But does document.body.onpaste mean using an IDL attribute? What 
distinguishes this from a simple property assignment?
