Au contraire:
"We discourage authors from using empty P elements. User agents should
ignore empty P elements."
- http://www.w3.org/TR/html401/struct/text.html#h-9.3.1
Unfortunately, the specifications are only useful if they get read.

<br> tags are outside the scope of this discussion. The spec, however, is
quite clear about empty <p> elements. See above.

These tags are, and should always be, interpreted as defined within the
specifications. The <p></p> element defines the beginning and end of a
paragraph, without implying visual styling of any kind. If someone
depends upon this tag to "move down a bit and then move to the next line"
they are setting themselves up for a fall if and when a UA decides to
implement their default paragraph styling in another way.

This is simply untrue. Why are you perpetuating this misconception?
> The effect of attributes to a <p> tag last until the tag of that level.
I don't know what you mean by this, perhaps you could clarify.
