html header and html body

[Checker1977]

But how does standard say whether content not wrapped in header and also not wrapped in body belongs to header or body?

You do realise that http and html are two completely different things?
The http RFCs don't deal with html, nor do the html specifications deal with network transport protocols.

I thought cornedbee already answered that: Unless it is SGML, it will be treated like it had a body around it.

The problem is I did not find from which paragraph of the Html Spec 5, the conclusion "it will be treated like it had a body around it" is reached. Any ideas?

I quoted the HTML 4 spec. It says that for all of html, head and body, both the start and the end tags are optional. So the elements exist whether the tags are there or not, and all that's left is to correctly sort the subelements into head and body.

For the HTML 5 spec, look at 8.1.2.4 for when it's allowable to omit the start tags of html, head and body.
For parsing, look at 8.2.3.1 and 8.2.5.5 and following. Note that the note in 8.2.5.6 is incorrect.
