Implementation strategies don't affect conformance. So, the actual 
behaviour here is that an authoring tool takes a conforming document, 
parses that into a Document; the user adds a proper table with only tr/td 
elements, and requests to save the document as HTML; the authoring tool 
then writes that document to a file.

No conformance criteria are broken if the user agent is assumed to have 
"converted" the document to a serialisable form by adding an appropriate 
<tbody> element and then serialised that.

If the user agent has not, e.g. it shows a tree of what it thinks it 
serialised, and that tree doesn't have a <tbody> between the <table> and 
the <tr>, then the browser has violated "A table element must not contain 
tr elements", under "9.1.2.5. Restrictions on content models".
