I'd recommend
http://www.w3.org/TR/html401/charset.html#h-5.3.2
Particularly
Authors wishing to put the "<" character in text should use "<"
(ASCII decimal 60) to avoid possible confusion with the beginning of
a tag (start tag open delimiter). Similarly, authors should use ">"
(ASCII decimal 62) in text instead of ">" to avoid problems with
older user agents that incorrectly perceive this as the end of a tag
(tag close delimiter) when it appears in quoted attribute values.

Not really. There's dozens of those, only a tiny few of which relate
to markup-significant characters.

Well, you *can* use that, but I can't think of a context where you're
forced to use it. As the spec says, it's a possible workaround for a
bug in some old browsers (I'd hope they're all obsolete by now).

Only necessary in a specific context (attribute value delimited by
quotes).

But the question wasn't whether &-notation is *allowed*, but where
it's needed.
