Hm.
OK: if %HTML.Recommended; is turned on, then the
example "<p>normal para<center>centered text..."
is illegal to begin with.
With this switch enabled, the content models for
CENTER and DIVISION expand to:
(H1|H2|H3|H4|H5|H6|P|UL|OL|DIR|MENU|DL|PRE|BLOCKQUOTE|FORM|ISINDEX|HR|ADDRESS)*,
all of which also imply line-breaks before and after,
so it looks like this can still work.
Suggested revision: Strike the statement "CENTER implies
a line break..." from the SUGGESTED RENDERING section
(since it's redundant), and add a note to the effect
that:
CENTER may only be used in conjunction with
the recommended HTML 2.0 features. In particular,
this means that CENTER may not directly contain
text (you must use <P> containers instead).
and replace the first sentence of IMPACT ON EXISTING IMPLEMENTATIONS
with:
None, as long as %HTML.Recomended; is also enabled
in the DTD for documents which use this feature.
> Given that, the DIV or DIVISION element seems like a better idea.
I think so too.
