If you look at the HTML 2.0 spec, <P> is a container.

<CENTER> implies a break-before and a break-after.  I.e. It implies a
logical change in structure, but what kind of change?  The following
are much better:

	<p>Some text
	</p>
	<p align=center>Some centered text</p>
	<p>some more regular text
	</p>

    or,

	<h1 align=center>This is a H1 heading</h1>

    or even,

	<address align=center>
	John Doe<br>
	jdoe@foo.org
	</address>

Another way to look at centering is that is an _attribute_ of the
current structural element and implies no specific structure in
itself.  I'd like to see some examples that use the <CENTER> tag that
cannot be easily handle in attributes.


I'd like to remind you again to look at other SGML DTDs (DocBook, TEI,
OpenBook) and see the type of markup they define that addresses the
issues you are trying to handle.  The DTDs I mentioned are used to
publish for _paper_, but fit well with on-line publication (eg. We're
using OpenBook for our on-line documentation).  Instead of trying to
reinvent the wheel, look at other wheels to see if they can roll you
down the right path.
